Pain relief and contagion

EDIT: Swab came back positive for HSV1/anal herpes.

I started my antivirals today and did use ab antibiotic cream ( i know it doesnt help herpes but the doc thought i might benefit from it incase i have a secondary infection). Still in horrible pain. Not even cold compression helps.

36 hrs ago I realized I have anal herpes (awaiting swab test results but it’s undeniable). I know they say the first outbreak is the worst but wow! I never would have imagined this much pain. My whole body is sore and aching, my throat hurts, my ears hurt, my pelvis is cramping and thats not even the affected region. I cant have bowel movements without excruciating pain and in addition to the pain of the blisters and lesions my whole vagina hurts and aches. Is it supposed to be this severe? I have a surgery next week and am not allowed to take pain killers so what have you used to help with pain on site or throughout the body?

Also…how do I keep anal herpes from becoming vaginal herpes? Seems impossible. Online just says to be hygienic but If blisters open they immediately leak towards the vagina. Is this preventable?
