I really don't know I do not get leg pain but, I have been getting some Right knee pain especially when exerting energy up hill and stairs, my ankles are always swollen and hurt like crazy and like we all know the bruising is part of the package deal. Sorry I couldn't be more help.
My function is about 40 but I haven't sucfered leg pains except cramp which I get in my ribs too. I get really bad knees but I've been told that's due to the steroids I'm on and the cholesterol tablets. Hope that helps :)
