A little over a week ago, I developed a boil/ infected blemish between my shoulder blades. It is red and painful. Honestly, I ve been squeezing it, thinking it was a zit, and that the pain would go away if I could just pop it. I have an appt. with a dermatologist a week from today. I feel a little lethargic today, but don t have a fever. Do I need to seek more urgent medical care? I read that if it is on the spine I should be concerned.
