I was installing some computer equipment and was being over for quiet a long time and felt the soreness once i straightened up. the next day the pain was so intense i had to crawl at a couple points throughout the day. I toughed it out and the next day was also filled with intense pain in my lower back. Although when i was laying down its just an ache. Day 4 pain continued and i started to notice a soreness in my left testical. Day 5 and 6 have been the same with the testical soreness going almost completely away. My question is that from what I've ''goggled'' it my sciatic nerve. I'm 32 years old and unemployed without insurance. I realize it should be checked in case it may be a kidney infection or worse. but it has gotten better from last week. What is my best at home medication or exercise for sciatic nerve problem?? And how important is it that i be checked???
