Be prepared for your arm in a full sling for 4 weeks. If they reattach the bicep, no using it at all during that time, as in lifting that arm with the good one to bathe etc.etc., and then light weight limits with different time frames for max amounts. My first one (left)took 8 months for a pain free recovery, but it was a sub pectoral reattachment. It sucked. Had the right done 3 years later but reattached to the humorous. Recovery was short and all but pain free. Different doctors, different techniques. You’ll probably end up going to physical therapy too. Neither arm recovered full strength in the biceps, probably 85-90%. Good luck with it. Shoulder pain sux.
