I have been worried about some weird feelings on my sides. The other day I had a lump in under my armpit that lasted 3-4 days and went away. Ever since then, I've been checking and feeling myself out for other possible lumps. I noticed last night when I rub my sides, below my ribs, and just above my waist that I have some lumpy type feeling beneath the skin. I can only feel it if I rub the skin with some pressure. Of course, now my sides are hurting because I guess I rubbed too much, too hard, and now it has become irritated. I can only feel it moving around on the inside. Is this normal? I can't remember ever feeling this before. I'm afraid it is lymph nodes or something? Do we have them in this location? Is it something else? This sucks!
