Strong Vaginal Ache

The problem started last april when i began experiencing a dull ache in my groin and the left side of my vaginal area. The ache became stronger and i was left in severe throbbing pain, starting off dull and becoming stronger, however the pain was constant. I tried painkillers but they did not take the pain away and no matter what i did, sit, stand, lie down i could not ease the pain which resulted in sleepless nights. When i was younger i had my kidney removed and as a young child i experienced many problems like chills and urine infections which caused a similar pain to the one i was feeling now, however this feeling was much more intense and could not be eased. I went to the doctors to find out what was causing the problem. A series of blood and urine tests showed the problem was not related to my kidney and when nothing was found after an external examination i was sent to a gynecologist for further examination. Still nothing was found and i was given cocodamol to ease the pain and told to travel to A&E if the problem persisted. I spent the rest of the night in agony as the cocodamol did not work and was causing nausea so i went back to the hospital that night, i was again given an external examination with nothing found, after several hours i was given antibiotics in the hope that this would solve the problem. After a few days of antibiotics combined with cocodamol the pain eased and i was soon back to normal after the sickness wore off. Despite my recovery i still did not know the cause of my pain. Since then i have experienced a dull ache from time to time lasting only a few seconds, recently however the pain has once again increased and after another unsuccessful trip to the doctors i am feeling very frustrated and helpless as i feel this problem will never go away and the thought that i may have to live with this on going pain is heartbreaking, i take regular painkillers which do ease the pain slightly but it is still extremely distracting and i find it almost impossible to get through the day, i would greatly appreciate any help or advice that could be offered.

Thankyou xx
