a mystery to me....medical type thing,can you help

[carole]

Ok i feel kinda awkward posting this, but just wondered if anyone has any ideas, two days ago i started having this unusual feeling in my side,right under my rib cage but right at the side,it is more around the side towards the lower back, it is not painful, just uncomfortable, especially when i sit and it is not going away, i feel stupid going to a doctor as there is no pain as such, and i feel fine,i find it difficult to even describe, but the best way is like when you are pregnant and the baby moves its feet into your side,kinda like a wave feeling,does that make any sense, no i am not having a baby lol, i have wondered if it is just muscle spasms, as i have fibromyalgia, but i have never experienced this before, and i am puzzled, i can feel it as i am sitting here on the computer and typing, eases up when i am standing or lying,it is really annoying and uncomfortable,and i am totally mystified by it, any ideas, or should i just make a Dr's appointment?

I should add i have been having very bad neck and back pain, but that is normal for me, and my muscles around both ribs are sore at the moment, and prior to this i used voltaren emugel for pain relief and i used a massage cushion on both of my lower sides to travel,that is the only two things i have done that are different to my normal,no idea if any of those two things have caused it or not.
