Hi I m 26, 5 ft 6 and 75kg. Recently I ve noticed a small indentation around 3 inches below my armpit on my ribs-sort of on the flat where a bra strap goes around on my left side. It s only visible when my arm is in the air. A month ago I had an ultrasound on my breasts and armpits as I noticed my left breast hanging a bit lower than my right and my areola isn t identical in shape. Theyre both around but the left has pointy bits as if stretched a bit. I also have had itchy armpits in both arms for months that comes and goes. I changed my deoderant to see if it helped. I don t have any rashes, scabs, no constant pain (just sporadic every now n then), no indents on breasts themselves yet and I can t find any lumps. I m scared the scan missed something as this is a new indentation. Please help
