I noticed twice that there is a small amount of thin, watery liquid drainage tinged with blood from the skin on my back. I am female, 65 years old, on hydrochlorathorazide(spell?) for high blood pressure, 5 foot 2 /136 lbs, active enough to walk up to 5 miles straight. I still work full time.
The first time I did not think much of it. The second time, a bit more concerned.
It is definitely from my back(no other orifice) I have a new rough, dark area the size of a dime.There is no pain, just this small patch lower back, left side.
