Permanent muscle atrophy/wasting after GBS

<p class=”_1qeIAgB0cPwnLhDF9XSiJM”>I had a minor form of GBS back in December 2009 ( I was 13 years old) , despite being almost 11 years since this happened, I have muscular wasting on my arms (wrist area) and calves which I was never able to recover despite exercising, going to the gym, physiotherapist, etc. Alongside the wasting I have minor tingling sensations and slight weakness, which do not really annoy as much as the wasting to the point where I avoid wearing short pants for example. My wrist area and calves area are skeletal</p>
<p class=”_1qeIAgB0cPwnLhDF9XSiJM”>From the majority of testimonies I’ve checked most people did recover their muscle mass after a few months, I’m curious if someone else has had a similar experience to me.</p>
<p class=”_1qeIAgB0cPwnLhDF9XSiJM”>GBS was minor in my case, I was only hospitalized for 2 days (only my feet/lower leg area was paralyzed) and I believe I was able to slowly walk in a matter of 2 weeks after I left the hospital. Despite how minor it was in my case compared to others, I probably will carry with me all these collateral effects that I explained above for the rest of my life. Thankfully, this has not prevented me from doing sports I like and other activity.  I could do 100 jump ropes in a minute, just to provide context that despite of this I can pretty much do any sort of exercise.</p>
Is there any sort of therapy, supplement, etc that could help with my condition at this point? I feel that I will never give up on recovering from the muscle atrophy
