I have been taking 100mg gabapentin for just at a month. Don t have health insurance...so Dr just took a swing, my back had been causing unbearable pain for 3 weeks, when prescribed. Pain pills and muscle relaxers did not help. This medication seems to help, but recently I developed a blistery rash in 7 or 8 different places, thought it poison something from yard work, but after reading the paper that came with the medicine it appears I am suffering from most of the possible adverse reactions. Is there a better option?
