After 3 months still not feeling 100% and wary of doing pullups so had an Ultrasound done, revealed some small tears in tendons and inflamed bursa.
Was initially a bit horrified but very interesting response from Physio
"Nah ! Don't worry too much. Accumulated wear and tear probably aggravated by too many pullups last year, just start being a bit more sensible about how many pullups you do and better still don't do any for a while yet. Alternate deadhang days with Upsidedown Row days, dont press too heavy, always be aware and be careful of shoulder - if your gut feel is to avoid an exercise, then do not do it, trust gut feel. ............. 3 minutes deadhangs a day not 7............. Come back and see me in two months. ................ Have a play see what you think is safe and act accordingly, slow down a bit, accept that you got to be careful from now on and one day you will have to do your very last pullup ever, just get used to the idea...............
