For the past few days, I've been feeling like my upper back is on fire. The feelings come and go and sometime spread to my lower back and arms, but they're not associated with any sweating or feeling unusually "hot" (other than my skin burning).
I've been to the doctor and they can't determine a cause. I've had this before
when my blood pressure was high, but it isn't high right now (I've checked).
Is this a hot flash or something I should be concerned about?
