I have had an extreme pain in my groin, that the doctors have not been able to figure out?

Several years ago I had an angiogram, everything was great. for the past 3 and a half years I have had an extreme pain in my groin, that the doctors have not been able to figure out. for the first three years it was so severe that I couldn’t do anything to change the pain. Since January I have had three events where the pain has dropped a little, still extreme though. last night was the last, now if I compress the vein at about the location of the insertion, my pain goes away completely. what should I do
