As title states, I have a tender feeling area (about the size of an egg (it's not shaped like a lump, it's not a lump but egg is probably the closest area size I can think of). I have felt it 'twang' like an elastic band when I have bent over and straightened myself up, and the sharp pain has taken my breath away, but it is immediately pain free afterwards. It is also tender to touch when I'm lying down. It doesn't feel muscular, as I can tense my muscles over it, and then when I relax it feels like it is under the muscle (I phoned local pregnancy unit, who said it sounded muscular/stretching of the muscles, but I'm not convinced for some reason). I've had this for the last 4 days and am 22+4 weeks. Has anyone else had this, and it has turned out to be muscular, or anything else? Thanks :)
