OK. I have had problems with itchy skin, mostly on my chin area. I find it gets worse when I eat a lot of bread (yeast). I also get cracks between my toes. After about 2 years, my old doctor (the guy was in his 70's), told me to put vinegar into a spray bottle and apply copious amounts to my chins and toes and let it air dry. I did this for about 5 days, and the cracks in the toes and itchy chins went away. My son is in the Army, they tell soldiers to pee on their feet when this happens ... yes it works! Vinegar will kill a fungal infection, as will uric acid (pee).
Now, I have this same issue on the inside of my scrotum; however, it has formed a quarter-sized purple area under the skin. The itching is crazy at night too. I'm thinking it is fungal, so I'm going to start hitting it with vinegar and see what happens. Guys ... another possible source of this fungus may come from masturbating. It's a good idea to make sure your hands are very clean before you do this activity.
(1) Do not be afraid to see a dermatologist and get a skin biopsy. If it's a fungus, it will show up unequivocally that it's a fungus through the KOH Test. It's a painless procedure. Anything beats scratching your scrotum and leaving open sores which sting. Only a skin biopsy will tell you whether you have a fungus. Fungal infections are the MOST common reason of itching on the scrotum. You have to rule out that possibility. If it is a fungus, GREAT. Treatment is topical or oral antifungals.
(2) If the skin biopsy's results are inconclusive, you need to see an allergist. Contact dermatitis might be a reason why you're itching in that area. People are allergic to all sorts of things. Including soap and certain underwear material.
(3) If you are not allergic to anything which has come into contact with your scrotum, you need to get tested for STDs. It's a simple and painless procedure to test for the most common STDs.
(4) If all of the above revealed nothing about your condition, you NEED to get tested for certain cancers. PUSH for it. Dermatologists or General Practitioners are not commonly keen on testing for cancers because most cancers which will cause itching (or pruritus) are very rare. Itching is common with Hodgkin's Lymphoma. Itching might also be a precursor for prostate cancer. The worst disease you'd want to have on your scrotum is EMPD, which can only be treated by surgery. You NEED to get tested for these malignancies. Otherwise, you'll be facing a plight far more tragic than just an itchy crotch.
(5) If all else fails, you'll probably need to consider the possibility that it's neurological. Certain neurological disorders can cause the perception of itching in the area.
In MOST cases, you will get to the root of the problem before (5). Be persistent. There is no reason you should be treating this on your own. If whatever you have been using had not cured your symptoms, then there is no reason to continue trying out new solutions. People far more qualified than you have the tools to identify and solve your issues. Pay them and let them do their jobs.
Note: Any dermatologist who continually prescribes steroid creams for your symptoms is CLEARLY uninterested in solving your problems. Steroid creams treat the symptoms, but it is NOT A CURE. Do not, under any circumstances, be satisfied with a steroid prescription. Visit another dermatologist if you have to. I'm sure doctors will approve of scans and biopsies if you demand for them. Systemic malignancies such as lymphoma is not to be taken as a joke. People do get lymphoma and itching is common in some subtypes. I know, because I had it.
Now, SEE A DOCTOR.
Diet does not cure candida overgrowth. There are effective clinical solutions for it, in the form of oral antifungal medication. These are proven by science. Feel free, though, to believe in homeopathy and voodoo magic.
I too had this intense itch on my scrotum. There were little elevated spots and leather skin on top of it. Initially it was one but after few days i could see multiple like it. The itch was unbearable at night and often get up. I went to three doctors and third one prescribed all suggesting a different cause. One of the most experienced doctor suggesting to be scabies, it turned to be scabies. I realised it when I saw another symptom of scabies rashes on back of hands. I used permathrin cream all over nody and some really hot showers.
The type of rash on scrotum fould vary but the infection could be scabies. So if your out of ideas try treatment gir scabies it easy and not harmful. Google for mire information on scabies treatment.
