It is open to the public and even though many times the information is helpful,it does not take the place of seeing you physician.\n\nBest of luck to you.

A doctor better examine you and you should do blood test before we can say anything. If tests where normal then it is likely that you have an overall body weakness. ALL your muscles are very weak and you should strengthen them. By strengthening your muscles the pressure would be on the on the muscle and not the joint! Another reasons could be of over weigth. You haven't mentioned it thought but if you are over weighted then you should control your diet. Again, I don't tell you to starve coz you don't wannu burn muscles too. \n\nIn conclusion, I think you should consult and always be in touch with a 'physiotherapist' (of course after you saw a doctor I mentioned above) to show you the proper exercises so that you can strengthen your muscles.

Sometimes, by the way we live, lack of sleep, poor eating choices, etc. Sometimes we're just hypochrondriacs stressed out for nothing. More often, it's not our fault.  It's bacteria, diseases & hereditary.
