I am a 16 year old female, about 161-165cm tall. I weigh approx. 74 kilos.I have a medical history of anxiety, depression, stress and minor issues regarding my heart due to stress.For a week or so , usually when i get in bed and lay on my left side , i get a tingly fuzzy feeling in my upper left abdominal area, just under my bra. It feels tender when i press it and if i press hard enough it almost feels bruised. What is it?
HI. This is classical sign of costo-chon Chat Doctor.  The pain at a spot you described and getting increased on pressure is suggestive of this. Advised
