I have a rather large bruise on my knee that I do not recall getting. When it started it was a green color nowit is a deep dark purple with a white center. It is tender to the touch. Its hard in the center with a small lump about half the size of a pea that moves. What do you think this is?
You should paint it twice a day with mercurial paint available in liquid form in market. In center, it is probably granuloma.antibiotic n analgesics suggested by your physician.
