Two days ago I noticed a scab and some missing hair on my bucklings back. I figure it is from either his vaccine he got about a week ago or a bee sting he got a few days ago. Yesterday the scab was almost healed (i applied polysporin) but a fairly large lump or abscess is there. Today the lump is even larger and there appears to be another one forming right behind it. Any ideas as to what. This is and how I can treat it?
