I've got this wierd feelings in my upper back few days ago, like I have a crawlings ants under skin, like my skin there is too sensitive and it almost hurt when clothes are on my back, like little shivers in my back... 2 days ago I've also twitches in my back under the rib. I won't go into the dillema if back twitching is also BFS, but has anyone get this multiple of symptoms on one place? I am not sure if it is sensory (twitching is not I am sure), I also get a lot more twitching in abdomen again (liver area), hands, arms, legs etc... But my back feels wierd now, little twtihing, little like itching, crawling, oversensitiv etc...Anybody know such feelings in upper back?
