Hi. My arms alternately and in different spots (right now the underpart of my upper left arm and the side of my left forearm) feel like they re being squeezed/pressed, a sensation similar to having my blood pressure measured. My BP runs slightly low (110/78 or so), which I inherited from my mom, who has fibromyalgia. This has been happening for a few days, and it seems to be getting worse. I m only 19 and have never had any physical health problems, except for fatigue, which therapists have told me is probably a symptom of depression. I also had a random small rash on my left arm last night, which is gone now. Does this sound like something I should get checked out, or am I probably OK?
