Swollen, hard abdomen with strange lightheadedness feeling

Hi, Back in November I suffered with some sort of a virus that kept me bedridden for about a week. After that virus, I was left with a severe case of Prostatitis and a Pericardial Effusion(water on Heart). I was put on Ibuprofen, Diclofenac, and various antibiotics. Two weeks later I became very lightheaded and felt faint, with chest pain and short of breathe and went to the ER. I was admitted for monitoring. That evening I became so dizzy I could not move. They gave me Meclizine. I then began to have severe abdominal pain. The next day I had an Endoscopy which was normal. Xrays that were normal. Ct scan of my belly, which was normal. An MRI-MRA of my brain, which was normal. Bloodtests were normal. I then had a Pharmachological nuclear stress test as I could not stand from the vertigo. Stress test was normal, but I suffered from terrible discomfort from the stress test. My abdomen hurt so bad and my chest-lungs felt like they would explode. Three more days in the hospital with worsening symptoms of chest pain, left side to middle, excrutiating pain in lower,middle and upper abdomen, as well as lightheadedness, dizzyness, and a nerve pain that went up and down my spine, legs,arms and groin. Doctors ordered stool tests which came back normal. After that stress test, I had a drop in blood pressure of about 15 points and my heart rate which ran at about 85-90, dropped to 60. 50 When I sleep. That is where it has remained to this day. I believe that nuclear biohazard almost killed me. I was released on the 5th day sicker than when I went in. No diagnosis. I went home and followed up with an internest. He tested my blood and stool again for various heavy metals, bacterias, and disease specific blood tests. All came back farely normal. I did find out that my bloodtests in the hospital were slightly bad in the liver. Albumin was raised and Gamma GT was extremely raised. Also heard I was dehydrated and my sugar was low, then slightly high then normal upon leaving the hospital. I went to a Urologist for several visits and had many rectals and a CT Urogram which was normal except for a bit of seminal vesicle inflamation and a prostate inflamation. I had a prostate ultrasound and a systoscope(sp?) More and more antibiotics which tore up my belly. Then I was told after having a venous dopplar that I had a clot in my arm from the IV's. Then started an aspirin regimen(650mg) for 3 months added to the ibuprofen(600mg a day) Diclofenac, simvastatin for cholesterol, carbamazepine for mood and nerve disorder, and still more stomach eating antibiotics. I was also put on Bentyl for the stomach pain and Nexium. Both of which did nothing. I went to a cardiologist at least 4 times and he did a Ct scan of my chest to look for clots and to check my heart, a halter monitor, an event monitor, EKG's, 2 echocardiograms and said my heart was ok. Two months after the hospital stay and after 5 CT scans, three of my chest, and two of my belly-genital region and dozens of more blood tests, the doctors all agreed I was on too many medicines that could be causing conflicts. I was taken off all medicines. Two weeks later my belly began to swell. Nerve pain was now all over my body. From head to toe. I had severe trouble breathing with stabbing pains all over my belly, genitals, neck,arms,back, and head. I went to three different Gastroenterologists and had barium swallows, an enteroscopy, more stool tests, more bloodtests for celiac, Iron deficiancy, vitamin deficiency. Thyroid tests and liver function tests. All came back normal, yet my abdomen continued to swell and be hard as a rock 24/7. I then was sent for a gastric emtying test which was normal. Doctor said I may have a bit of a fast metabolism but not Gastroparesis(paralysis of the stomach) I was sent for 24 hour cortisol test which showed a slightly hi cortisol but I was in pain and nervous so It may have been nothing. I was checked for lead poisoning and that was negative. I continued to see my family doctor to no avail and saw another Neurologist for the nerve pain and lightheadedness. He gave me Carbamazepine again for the nerve pain. I was on it for about 10 days when another doctor got upset with that decision and took me off it again. The doctors started to say at different appointments about a Neuropathy. I saw a neurosurgeon and he said that I need a good neurologist and a nerve conduction test. Nerve test turned out normal. The little nerves that are in your legs and back and genitals and stomach etc. cannot be tested. I went to a Tertiary hospital to see a better Neurologist, and he was a waste. He did reflex tests and blood pressure tests and said that I should go to the Mayo Clinic in Minnesota for a possible Autonomic Dysfunction, cause my blood pressure swings with positioning too much. My heart rate swings too much. Mt digestive system tests normal, but I still have pains everyday and still after 5 months, have a distended hardened abdomen which causes bad shortness of breath at times and palpitation( pounding heartbeat) regularly. I also have bad lightheadedness most of the day every day. I get nausea and throw up from time to time. It seems that although my belly never shrinks anymore, that after I eat, it swells even worse and I get terrible SOB and irregular heart beats. I am now seeing an Endocrinologist which is running a bunch of tests. If they are normal, I will have to somehow go a thousand miles to the Mayo Clinic for my last hope. I apologize for such a long post. I appreciate any advice from doctors or people who have the same things going on. Right now, my symptoms are bad back pain from tailbone to my head. Mostly in the lower back. A swollen, distended abdomen with rigitity. Difficulty breathing, lightheadedness,pains in my head, swings of constipation to diahrea and still that never ending chest pain on the left breast area and palpitations. I am no longer on any meds. The doctors don't want to make things worse with the symptoms when they cannot figure out what is causing them. Since November, I have lost 30 plus pounds without dieting. Although my appetite was bad, I forced myself to eat and even drink protein drinks like ensure or boost. I did notice that I get sick after drinking Ensure and soymilk. Diahrea and vomiting. I also was taking Lorazepam for a number of months cause the illness scared the pants off me. I have stopped that medicine almost cold turkey. I am getting some withdrawal from that. No diagnosis as to what is swelling my belly, causing all this pain and lightheadedness. Before November I was fairly healthy. Although, about 2 years ago, I lost almost 25 pounds very quickly without dieting and my gastro doctor could not diagnose anything then either. I had at that time, lower left abdomen pain ongoing for months. Now, most of the pain in my belly is either in my lower right abdomen, or a little discomfort under my breastbone, but that can be from the swollen belly? I have not had any scans of my belly since it has swelled. They just refer back to the CT scans prior to the swelling. I am at wits end. The doctors all agree on a few things. I am sick, my symptoms are real cause they can see my swollen belly, but they have a mystery that they cannot diagnose. Thanks for reading and any help you can give me. I am a 38 year old male. No drugs, no smoking, no drinking. Thank you. Brad
