Hello. I Am Currently Treating A Cold Sore Outbreak With

Hello. I am currently treating a cold sore outbreak with a prescribed medicine. I get blisters all over in between my teeth and around my gums on the right side of my mouth. I also get pain in my neck, and generally all over the right side up to my scalp. Yesterday, my face began to swell, and is now extremely tender to the touch. The last time my face was swelled, and super tender like this, they diagnosed me with erysipilus (sp? ). Should I be concerned, or should I continue with treatment as is? Also, is there anything that I can do to help ease the pain and reduce swelling? Thank you.
