Hello. So I've been going to various doctors for over nine months trying to figure out what could be causing this pain in my side. It comes on randomly yet suddenly and can be very painful. Every time I exercise the pain gets so back it is physically painful to breath although i am in decent shape. My face has also been twitching along with slight twitches in my arms, legs, hands and feet. I have been overly tired for sometime now but that may be due to stress. I also get very dizzy while standing up too fast and i have started to stutter and it is hard for me to speak sometimes if that makes sense. Could this be MS?
