Hey Jefj   I will second this.  Yes MS can definitely is capable of causing pain to most parts of the body including legs.    In an article about pain and MS author Gina Shaw states that:  "In a national survey of more than 7,000 MS patients, 70% of them had experienced some kind of pain, and at least 50% were experiencing some kind of pain at the time of the survey."   So you are not alone.   You can have pain due to spasticity which can cause painful contractions in muscles.  You can have pain due to stiffness in the legs. And you can have pain due to the fact that if your gait changes even slightly, you may be putting more pressure on certain muscle groups by walking differently.   I have had pain in both legs when I have had a miserable day dealing with leg spasms.  It happens especially when I am lieing in bed wanting to go to sleep.    I would definitely tell your doctor or neurologist that you are experiencing pain and maybe they can give you something to treat this.  Other than meds some people use massage or physical therapy to help.   Do take into account what Lisa has said though as well...just because you have MS doesn't mean every pain can be attributed to it.  Make sure you do tell your doctor about the pain so that he or she can get to the bottom of what is causing it.   I do thank you for your question and I hope your leg pain goes away.
