I've been getting back into shape for the past 9 months or so, and have recently developed a sharp pain in my elbow that only lets me throw punches at around 60% of my total power. I cannot curl much weight due to this pain either. Shadow boxing today I noticed that even my form is different because of this pain. Even though my punches were hard, they did not look the way that they used to. The elbow started hurting after one strenous chinup workout, and I always try to give it 2 weeks or so to heal, but now after tricep-iso pushouts, the bows are just hurting again. Its very hard for me to abstain from working out or throwing hard punches for even one week, two is worse, and I don't want to miss weekly BJJ classes even with the frequent armbars. Any tips, advice or anything would be appreciated.
