I was taking 200 mg of Lyrica twice a day for upper back pain that goes up my neck. I turned a 4 wheeler over and hit my head and back real hard on the ground. My cobra insurance ran out and I couldnt afford it so I am now taking Gabapentin 300 mg. twice a day and I hurt like I did before I starting taking the Lyrica. Is there a stronger dose and can I take it?
