What Does Pain In The Testicles Indicate?

For About 10 years now i have been experiencing pain that has been from my testes leaving my scrotum up into my groin area, this happens quit often and only when i happen to use meth that it seems to do this , but it is very very painful, I try taking a bath in warm water it used to work years ago but now it doesn t , i have tried to put a heating pad on them and i take Advil ,Tylenol , pain relievers , but they don t seem to be making much of a difference , I am not a pill taking person, id rather deal with the pain but it has been unbearable, its a constant pain in both of them but my left one seems to be having more pain then the right . Also my lower back and kidneys hurt as well. I have tried staying hydrated , sometimes it works and sometime it does not, I have went to the hospital, they have taken Kat scans, token blood and urine tests etc. and the hospital gave me antibiotics which did not help at all, I get My Insurance in 2 months, i don t know what else to do. what are all the possibilities and what other information can i provide that would better diagnose me, could u give me question that would better assist in figuring the possibilities to fewer possible diagnosis?
