I have more armpit fat on my left armpit compared to my right. I feel it more whn i bend my hand and usually not visible when my hand is upward.It's soft fat with no lumps inside i checked very deep just few veins and there is no pain. I sweat a lot and keep getting heat bumps and pimples in this hand as i seldom use this hand. i do work from home sitting in a sofa all day and i rest this hand most of the time. I work out thrice a week but don't get much time to go for walks. I used to have to a very active lifestyle before pandemic which completely changed due to lockdown. I also sleep on my left hand most of the times. I have gained 10kilos in last two years during lockdown. Is it a matter of concern. I'm not sure for how long it's there.
