Hi there, I haven't been formally diagnosed yet even though the Neurologist said probably PPMS. I was prescribed Gabapentin for L'hermittes which I have had now for 3-4months. It is not painful just a rather odd sensation which takes me by surprise and is unpleasant and then it just sort of tingles right down my leg and around my hip. I started the Gabapentin for a week but I felt so weak that I have decided to stop it and live with these sensations. I know you have to give all medication a chance to take effect but I thought I am not in real pain and I would never know if it's the MS making me feel weak or the Gabapentin! What do you think?
