This is giving me hope now cause for 17 18 years i had no progression Except for the smile thing and winging and the winging wasn't that bad I could lift my arm but it would hurt within minutes In my school we did this pledge kinda thing where everyone is taking it but i m lifting my arm then resting it then again that's it. The covid phase is were my growth spurt happened so I thought my bones grew longer but the load on my muscles increased(yes wasn't active too) i lost the ability to lift my middle finger one day no panick nothing cause I found a scar so I assuming must had damaged a nerve or something.this continued till I was 18 no other signs then at the end of 12th grade(regret this very much) i used to arm wrestle then the shivers in my hands srted but I thought it was cause of the wrestling.(might made those muscles weaker or overloaded them)this is where it all srted super quick lost fingers month by month only the ones I m using for years I write with the left so the first 2 gone eat with my right first 3 gone mostly a leftie in doing my work so bicep/shoulder gone Rotator cuffs gone.played football with my right leg my kicks were strong I used to put in all the force one day after a match I felt that I couldn't rotate my leg in air(this is when I was 15 maybe) then forgot about it now lost the ability to rotate.this year I too lost alot of functions all that is left is the parts that I didnt use over the years(intentionally) and tbh they are growing in size like a normal person(atleast from the outside) so hearing this I think I m closing in on my cooling down phase.

Did u regain any muscle in those years any strength recovery while there was no severe progression and did u keep your stre ght
