I have a lump on the inner part of my right thigh approximately 1/2 diameter and roughly 6 -8 from my groin area. It has a small pinhole head that is off white in color and the remaining portion is deep red, as though it is filled with blood. I have had this once before and I popped it like a pimple and blood came squirting out and it took a couple days for the bleeding to stop. I m not sure if it s a boil or cyst and if I should make an appointment to see my primary care physician. Thank you!
