Now I have fully accepted that fasc is a part of me and that Im ok. So will you be over time. Only advise I can give is to take it easy on things and that these muscular stuff is pretty normal for many. Even my doctor have these things. Just dont dwell on it. Move on ASAP!
Im 46 years and do some races on my road bike btw. I have an avg. on about 38 km/h for 160 km and improving. Not too bad. BFS shouldnt prevent you doing stuff that you like

Best wishes too all of you.
