Four days isn't very long, not to mention that the dose is typically increased until you find the right level and pain relief. I would think if it was going to help, you might have had SOME sort of sign...but on that low of dose, you may not have.

I would call your doctor back and discuss your side effects and ask for his/her opinion. Your side-effects are typical at the start, but it may not be appropriate for you to continue with children to watch...if it affects you this much.

Many of these medications have these types of side-effects. I took Neurontin for a few years but eventually maxed out on dose and still had pain. I could not take Lyrica due to the zombie effect and Cymbalta was just a horrid experience.

You may do better with some of the supplements MrsD suggests. Have you tried any? What about Rx Lidoderm patches? Biofreeze?

Maybe your doctor will have a better suggestion.
