Twitches do indeed happen to people with MS. MS is a disease of the central nervous system. When the CNS is damaged by scarring of the myelin, then symptoms occur. These can be anything imaginable depending upon what part of the CNS has been damaged. These can range from numbness, tingling, twitching, tremors, sleep disorders, vertigo and balance issues, migraines, seizures, spasticity, cognitive problems, vision disorders, bladder and bowel dysfunction, blindness and paralysis.
Unfortunately, Medstudent, all of your symptoms can be associated with MS. Fortunately, they can also be associated with a number of other more treatable illnesses (migraines, anxiety and panic disorders, lyme disease).
Momtothree is correct that you need to have lyme ruled out. This can be extremely difficult. There is very poor agreement as to how either of these diseases is diagnosed and worse yet is that they have polar opposite treatments. One boosts the immune system the other means to modify/suppress it.
Good luck. We are here with any questions you may have. Below is a really good explanation of the diagnostic process of MS. Worry and stress can and will exacerbate any disease. Try to find ways to manage that stress!!! It is one of the harder and more important things we do.
I just read of your heat sensitivity on the lyme board. Heat sensitivity is a classic MS symptom. Of course it can be caused by other things such as lyme disease, but in the old days before MRIs, an MS diagnosis used to include a hot bath test. That was the test; they would do full neuro exam then put you in hot water for twenty minutes then repeat the test. Heat is a miserable thing for most people with MS. For some reason it is nearly universal for MS. Please make sure you mention this to your neurologist on Wednesday.
I hope you see this. I don't like posting on the Lyme board, there is a lot of controversy surrounding lyme and MS. Many lymers feel that MS does not exist and it is undiagnosed or misdiagnosed lyme. I know for a fact that I DON"T have lyme. I had a western blot and I did pay for an igenex test and I am not sick like lyme. Lyme people talk about flaring nearly every month, they have signs and symptoms of infection. I don't have that. My symptoms are very much static and stay with me day to day. They stem from brain damage from this disease.
I have not seen a LLMD and am not inclined to do so. Just so you know.
