I have pain in my left lower back that runs through my left hip and into the left side of my groin radiating into my left testicle. I have been in pain for about 20 hours now. what could cause this and what can I do for it? I have had a growing lump on my hip for many years now. it started rather small and is now about 3 inches long by 1 inch thick. it does not hurt in anyway. I know I should have had it looked at many years ago but I have severe anxiety attacks and I cant take many medicines. They set my mind racing and my heart and it makes my throat feel as if its closing. So you see my dilemma.
