In reply to Jen-na-far:
I had a similar thing. A tear in some cartilage and damaged ligaments in the TFCC. For me pull ups on jugs were fine, say on a crimp, got a strong sharp pain. Pushups were a no, (and still are a bit iffy 2 years on.)
I did it climbing indoors
. Just from grabbing a hold with my wrist bent outwards.
I thought it would go away as I didn't know what was wrong, after a few months I went to a physio, who then got an MRI done...Then it was off to a surgeon who stitched up the tear. Then a few months of recovery. All up had about a year off. Could have drastically reduced that if I'd gone straight to the physio.
