Hi, I Was Bite By A Brown Recluse Over A

Hi, I was bite by a brown recluse over a year ago. I have a large dollar size scar from it on my thigh. I keep getting sores that start as pimple like sore that itch and burn to start if scratched form a hard white core that really hurts. They fill with puss and slowly go away after plug is gone. They leave scars. They show up anywhere.
