Hello y'all 
24 yo male here, I have been experiencing non stop burning sensation or pins and needles feeling in my both legs and feets, it gets way worse when I'm lifting weights and when I'm wearing socks and shoes. 
It's so weird and odd, I feel so frustrated and lonely, not a single doctor or a specialist have a single explanation ,did blood tests, MRI, nerve screening etc....  Nothing is found. 
So sad and desperate about it and no one I know ever experienced that. 
Did anyone had this issues before?  Especially the burning feet when lifting weights?  All the answers and support is appreciated :)
