It sounds like you're on a typical course of meds, so that should be OK. The important thing is getting them soon enough. You need them within the first 3 days of the symptoms developing, or they're not as effective. It's really good news that rash hasn't spread. My husband got Shingles twice in a few months (while caring for me) with only a couple of spots and avoided the pain. I didn't get the meds soon enough, so I was in pretty bad shape.I'm still dealing with the pain after the shingles itself has cleared up (called PHN).
Here are some important things to remember. You are SICK! The virus has multiple symptoms, the rash is just one outward sign of it. The virus causes pain, fatigue, abdominal problems such as nausea or bowel issues, and other, odd symptoms.Many, including doctors, just think of shingles as The Rash, no it's much more than that. If the pain is worse, ask for something to deal with it. It can help you heal more quickly as you rest and avoid stress and whatever makes the pain worse. Where is your shingles? That will make it easier to give good advice.
The typical treatment consists of:
1) the anti-virals such as Valtrex.
2) for pain either Neurontin (Gabapentin) or Lyrica are prescribed. Both affect the brain by disrupting the pain signalsl. Often you need to slowly increase the meds until you find the right level to help. They can have nasty and frustrating side effects, but for some (like me) the pain was so bad, it was the only way.
3) rest and avoiding increasing the pain. Mine's in my back and chest, so I avoid lifting, bending and twisting. In earlier stages, sitting too long. You do NOT want to aggravate the nerves more. I was off for two months.
4) pain cream or patches either prescription or OTC. Aspercreme with 4% Lidocaine either in patches, lotion or roll-on is helpful.
I also use extra-strength Tylenol and a prescription NSAID I've been on for years. There are other treatments or aids such as distracting yourself (Yes, it IS important to not focus too much on the pain), showers, heat or cool packs or prescription pain drugs.
You need to be your own advocate and learn as much (despite how discouraging it is) as many doctors aren't familiar with it. These forums area very good sources of info. Take care, we're here.
