Hello, Bethlem Myopathy

Hello everyone,

I am 27 years old, and i have BM since age of 3. I can walk, but cant use stairs or get up from chair( I use table/desk with elbows to get up). I had the tetanus surgery since the 16 age, but i m back on fingers.
I need help if someone use proteins, amino acids or creatine? Do they help? I just started using whey protein and glutamin.

Thank You,
