So sorry to hear about
your neuropathy problems. I too have it bad in both my feet and legs, but lately, it is mostly in both of my feet. I have been on Lyrica for over five years and it helps somewhat, but lately, it has been a real struggle. I also take pain medication and that helps only sometimes too.
To answer your question about the cost of Lyrica, it is expensive. I have insurance, so I manage through my prescription program. Lyrica can only be purchased under its brand name and not generic yet. I would suggest you try it though. I tried Neurontin on two separate trials and it never worked for me. The Lyrica had side effects at first, sleepiness and weight gain, but it worked on the pain initially.
I never tried taking Cymbalta, as I take other meds for depression.
Good luck and let us know what you decide.
