what is this small round solid slightly red bump between upper arm and breast that's not moveable? . there is only 1 bump and i have had it for almost a month. it is on the skin not underneath it. i am a 24 year old female. i have a dermatology appointment on the 21st but i'm a bit anxious about it and wondered if there were ideas about it.
the good news is this bump is on the skin. usually lumps on the skin aren't serious (in other words not like a breast cancer which usually resides deeper in the tissue). several things could cause a bump like you describe. it could be a boil for example. if so the good news is it can be drained treated and probably won't return. other than that i wouldn't want to speculate. you've done the right thing by scheduling a medical appointment. try not to feel too anxious. soon you'll know exactly what this thing is and then you can move forward with a treatment plan. feel better soon!
