Hey uhh... For the last little while, ive had a strange growth/bubble behind my bellybutton. Not inside it, like... Inside me. I put my finger in my bellybutton because I felt a little pressure, and I felt some hard-ish object under the skin. I pushed a little harder and it seemed to burst, and wasnt there anymore. Then the area felt like I just had a needle, torn up inside type of thing... Does anybody know what this is and if it needs medical attention?
