Trigeminal Neuralgia and MS?

Heyas.

Brief history. Been ill for 12 years, diognoised with 'possible' MS after a spinal lesion was found in 2004 and put on Copaxone injections. After a year doctors told me it wasn't MS and took me off drugs. Then I was diognoised with Lyme and put on IV antibiotics for a whole year, got better (this was finished in August 07) then been getting really ill again, all symptoms, numbness, fatigue, depression, bladder probs, etc.. but was getting really bad head pains like electric shocks in certain parts of face which are now daily and so painful I feel like dropping to my knees in pain.

Saw a nuro after my legs were so numb and I was in so much pain I couldn't get off the floor after collapsing and taken to the ER last month.

Saw him on Tuesday and he thinks I have Trigemianl Neurelgia and I am having 3 hrs of brain and upper spine MRI's this Tuesday with and without contrast in an open MRI (very freaked by small spaces!)

SO my question is this?..................how common is this condition with people with MS.

Oh, and the nuro who is setting up these tests is an MS specialist, so after all these years and treatments for other stuff, I guess I could expect a possible MS diognosis...AGAIN!!!! although I think in my heart I have know this for a long time!!

Thanks
