Hey.......

Everytime I throw a punch i have a crack noise in my shoulders and i'm really starting to worry about it. I dont feel any pain, but i do feel like it restricts my shoulders movement a little bit, also, sometimes when i throw the right hook i feel like my shoulder is going out.

everybody says you can fix it with prolotherapy. Does anyone of you know some boxer that has get prolotherapy?

thanks in advance.
