Welcome to my world.but mine is in both thighs
Every morning I wake up feeling like I spent the night doing squats .and it has not gone away for well over two months now.walking helps a little but,I look like just got,of a horse.as for,the soreness I have that under both arms.somedays it hurts to get dressed.as my dad is working for two weeks I had to walk the dog twice a day.
Proper walks .its not helped ,but I do love my walk times as it gives me time to go off in a world of my own for two hours aday,
Even right now I can feel like right thigh pulling like a *****.
Your so not alone with this, if u have a bath which I don't, u can try Epsom salt, that's meant to help at night xx
