postherpetic neuralgia
"I have Nerve pain from shingles (postherpetic Neuralgia)The side effects of this medication were terrible for me.  I gained 15 pounds in 1 month, am so extremely tired that I can't function during the day, and my blood pressure had dropped significantly.  I was on blood pressure medication and had to stop it.  My blood pressure range is now 78/54 to 87/60.  I am awaiting for a call back from my physician today.  The fatigue is terrible.  I decided that I will suffer with the pain and titration off of this drug (I have only been on it for 1 month). The side effects are too devastating."
