I have this tingling feeling in my back like by the left shoulder blade that sometimes gives little stinging feelings down to my hand also.It is usually always there. Sometimes it goes away for awhile but it comes back. Also I i have been feeling kind of full like i don't want to eat and i also feel like i have to use the bathroom all the time like i didn't completely go but if i try to go again i cant. This been going on for like 3 days with the bathroom part and the tingling maybe a week.
