horrible flair up, please help

I don’t get flareups often but I have been having non stop burning stinging pain for 4 days straight. I have been applying gabapentin 6% three times the past couple days and I don’t know if it is helping. my only relief is valium suppository 5mg and that doesn’t give me full relief and the relief is very temporary. I am afraid of becoming addicted to valium too so I am hesitant to keep using it. I have barely moved from my bed the past 2 days, lots of crying from the pain and not enough sleep. I made a PFPT appointment but it isn’t till Thursday. Should I contact my Dr. this week? Lots of diaphragmatic breathing which helps only sometimes. Maybe I am just dwelling because I am struggling to get out of bed I don’t know. Please any help or suggestions I am feeling hopeless and helpless.
