Hi, I ve had these boil type bumps (red, raised a bit on the skin, but deep and round under). They start off very sore to the touch. They started to appear 6-9 months ago. Usually just one will appear and go away in about a week. They have shown up mostly on my upper thighs. I have two now - one on the back of my leg/just at the end of my calf muscle. The other around my shoulder. I m a 52 year old white female, in good health, no medications, 5 9 , 149 lbs. No change in diet and or soaps, lotions, etc. I d appreciate any info. I will make an appointment with a dermatologist, but know it can take 3-6 months for an appointment. Thank you
