Almost 2 years post op-pain

I had a very successful surgery (intra muscular transposition) in that my numbness basically went away immediately. No issues after 6 months, all has been good. Fast forward to doing light weights, trying to tone my arms, and by light I mean starting with 3 pound weights and going to 5. Started to get an ache in the elbow. Rested, ect…. Now it’s achy all the time, some pain but not in the same areas that I recall having any pain before though the pain does move around. Sometimes it aches around the wrist to and side of arm. The same side that was effected before the surgery. Not going to lie, I’m really bummed.

Anyone else experience anything similar so far out from surgery?
