Ulnar nerve transposition: 3 months post-op questions.

I’m 18 years old, and I had an ulnar nerve transposition on the first of October, and I’m now nearly 3 months into the healing process….I can fully extend my arm, I have no tingling / pain in my hands or anything like that. When I raise my arm above my head and lower my hand below the back of my head (like an overhead tricep extension) there’s a tiny, subtle clicking nose near the incision sight towards the middle of my elbow. Is this normal? Or should I be concerned that the nerve is experience subluxation again?

For those of you that were in my position, is wearing an elbow brace / support sleeve during the day worth it? Is there anything I can do to further a healthy healing process? Thanks!
