I'm waiting to have my MRI next week. I've been having all kinds of leg issues lately, etc. For the past 5-6 months, I"ve had pain when taking a deep breath upon wakening along with pressure/discomfort around and under ribs/diaghram area. This happens 5-7 days a week (at least). It takes a couple minutes of taking shallow breaths to have the pain dissapear and to be able to fully expand my lungs. The sensation is as if I've been hit in the ribs and also feels like I've done a hundred sit ups. I know it sounds crazy, but it's the most frightening feeling and the doc didn't say too much yet. I'm 40 years old and basically a very healthy person with the exception of these new symptoms. Has anyone with MS experienced this? I'm not diagnosed...still in limbo.
