i was bit in the bicept 3 and 1/2 weeks ago by a great dane, I did 2 rounds of antibiotics the first was 1 pill for 7 days the 2nd was 2 pills for 10 days, its still red and hot, itchy, feels like someone is ripping something deep in my arm and doesn't seem to be getting any better. i have been to the Dr several times, not sure where to go from here
