I have a sprained calf muscle and it has caused bad pain in my knee . It is very hard to bend my knee. I have been to of but it is too aggressive and causes me several days of even more pain after. I have been to several doctors but I don't feel I'm getting good help this has been going on since November. I am now taking 800 ibprophen 2/day....I ice and do some basic stretches. Do you have any suggestions. I can barely walk.
