My wife (age 70) has been dealing with MS for more than 20 years. She has been on 200mg of Carbotrol since the beginning twice a day. Over the last few years she developed Trigeminal Neuralgia which is pain on one side of her face and we have dealing with that as best we can. Now the pain has increased to a level 10 and it's time for surgery. She has a neurosurgeon to see in Pittsburgh Pa. on the 26th of March and we are suspecting he going to do a radiofrenquency ablation. Has anyone here gone through this. Any help or information will greatly appreciated.
