In pain

So recently I thought I was having a pad rash on my vagina. I went to the doctors and she swabbed my rash for herpes and gave me a blood test. The blood test came back negative but the culture test had not come back yet. I’m in so much pain down there. She prescribed me the antiviral just in case it is herpes. It’s day 3 and I’m not feeling a ton of relief. Is there anything I can do to stop the pain?
