I'm not long over 2 months of agony with this. Fortunately I have a very good physio who I've used for a previous shoulder injury that got me back to health.
Weekly visits for a month with the old electroshock acupuncture stuff with 2 weeks of twice a day unloaded strengthening exercises building up to weighted exercises have done the trick. I can still feel a weakness on the problematic side but I'll get it stronger in time.
After I started feeling better I stayed off the bike for a month along with other activities.
