For about 2 weeks I've been having an aching pain I've never felt before in my life. It's like my lower chest/rib cage has been beaten thoroughly and it just aches like you would not believe. Sometimes it makes breathing painful, other times not so much, but probably more often than not it makes me feel short of breath - kind of like I can't get a deep enough breath. So far I've been able to treat it with ibuprofen (800mg) but a couple of times it didn't matter how much I took, it just didn't ease up. I haven't talked to my doc about it yet, I'm hoping that it's just something that will pass, but I think I remember reading somewhere a while back about something like this being related to MS. I can't remember where I read about it or what it was called, so I'm hoping someone will know what I'm talking about, or maybe I'm just having unrelated issues.
