I have something like this but on my low back right side. I've had it for 3 years it has gotten bigger and spread. It burns, itches and hurts when pressure is put on it I wish I could post the picture to compare it looks bruised until it flares up when I do any lifting or excessive walking or standing then its big odd shaped bumps under my skin. I've been to several different doctors over the years and have not been able to figure out what it is or what to do about it. I google searched my picture and this was the closest to my issue
