So here goes..... I have a indentions in my right upper buttock with skin discoloration of white. It happened overnight. It does not hurt. Its about 1 by 1 1/2 there s no piticular shape (maybe circular) but looks like it might have a crossing lines at the bottom..never had any injections of any kind in the bottom..no injuries. No falls..I can fit my thumb in the area..went to my family physician and he thinks its from a steroid injection. (except I haven t had any ever) then his next professional opinion some fat has melted away, but I would have noticed that. Im 5 foot and weigh 110 pounds...so anything melting off my body...I would notice. (Its a hole in my body...like bone or large mass was just taken out ), then So my physician is sending me to a general, plastic surgeon for their profession opionion...Im more concerned with making sure whatever this is ..is not harmful..not interested in fixing it if there s no need to, healthwise, not wanting to have any surgeries)
