I have a pain my leg in the last few weeks. There is no cramping or burning or sharp pain. It's just a light pain. Is it MS?
While pain is a potential symptom of MS, it is really a symptom of so many things that it is impossible to say that it may be related to MS. When you have new symptoms, your body is trying to alert you to something. Call your doctor, describe the pain, discuss the possibilities, and see what can be done about it.
Besides the pain in your leg, do you have any other reason to suspect MS?
