I am 29 year old male recently I notice something

Patient: I am 29 year old male. recently I notice something I Can’t Feeling anything in back side of the left arm (touching, pinning, pinching). I think it’s growing to palm side. When I put that portion on any material like char’s hand rest there feels like frozen. Just now I touch there with water, I can feel that water but its feels like I touched on a hard place.

Symptoms: Freeze .
