I tried popping a pimple on my knee which only half popped I suspect I ruptured the pimple in 2 days my knee has swollen up to the size of my upper thigh an area around the pimple under the skin is hard, it is very painful to the point that I am limping, I am using ichthammol ointment that seems to be drawing out a lot of puss and fluid. I have noticed though that when I move around that area starts getting hot and I start getting a slight fever where I feel cold but have a high temperature is this something I should be worried about
