Bone & Muscle problems

From last few years I am suffering from Constant pain in legs and sensations in legs and thighs and knees. I had consulted with doctors no of times and also had all the tests,but couldn't find any abnormality in the test.

I am a 23 year old female and have been having a dull, achy kind of soreness in my lower back, right above my glutes. This has been happening for the past 3 weeks and the incident which set it off was me doing a deadlift in the gym. It has not affected my movement as such and I have been able to stretch and work out as usual. But the soreness still persists. I don't know if it's just a muscle problem or maybe something serious like a herniated or slipped disc. The pain is mainly confined to the lower back. Please tell me how to go about this. I don't want to get crippled and be in a state where I'm never able to go to the gym again.

I am having pain in my left wrist and forearm when i do saputation or when i rotate it. This might've happened in the gym as I workout regularly. During one of my sets, I think I didn't get rid off the weight in a proper posture. Further exercise involving the wrist and forearm might've alleviated the issue.
