Yes, as a matter of fact, just had my surgery in late February. It was exactly what you have a Distal detachment (rupture from the elbow), this needs to be treated immediately or if not they have to use a cadaver tendon. Get to the DR. and get that MRI. the MRI sucks you will be laying on your side with your arm crammed in a very uncomfortable angle. since im a big guy I barley fit in the machine, they literally had to push me in.
Recovery is long and tedious don't expect to train for several months and even longer doing any bicep related exercises. what ever you do, do not train to early, if you detach again, you start from the beginning. use this time to let your body recover (if using gear). GH will help greatly, as told to me by my ortho and rehab specialist. 2 ius is plenty 5x week. more will be a waste. get use to doing light legs and lots of cardio. I looked at it as a nice break and let my organs and shoulders rest and heal. as of today I am still not lifting on using bands in my garage LIGHTLY. due to covid19 as well no gyms are open around me. if you have any other Q's let me now.
