I have MS and recently diagnosed with TN....Been prescribed neurontin 400mg 3x day.This I have been on for about two months with no help with TN,but has helped with numbness in hands,I have daily headaches along with major pain from eye down to corner of left mandable,,,,with major ringing in ear and pain on the bone behind my ear,,,,all on the left side,I must tell you that this is the most terrible pain I have ever dealt with.It is hard to explain the pain.it comes and goes and at times will stay for a couple hours with such intensity that all I can do is hold my head in a pillow and weep!!! My reg doc did prescribe dilaudid 4mg that only takes some of the pain down to a more comfortable level,My Neurologist has prescribed 400mg of neurontin and said this should in time take it away??two months later I am still dealing with this horrible pain??? I cannot deal with MS and TN together,,,feel like I may as well be dead!! soooo.with the ignorance and self rightousness of my Neurologist who seems to not give a damn,,,,I blame him for what I do!! BYE,,,,,and god bless the living!
