Has anyone gone from Gabapentin to Lyrica then back to Gabapentin for your nerve pain. I was on the max dose of Gabapentin 3600mg per day then to 600mg Lyrica aday I have had alot of break through nerve pain across my upper and lower back I know this is ms nerve pain a as I have gone to er several times with this exact pain and it has always been ms related. I am not sure if im just maybe starting a flare even though I am on Tysabri and it is not as likely or the Lyrica is not working for me. Have any of you had this scenario? Thanks!
