Headache with Nerve Discomfort

[Tania2007]

Hello, I'm a 27 year old female and have been having strange problems with my nerves for the past couple of weeks. I've been generally sick for over 2 months, beginning with something that seemed like a common cold. This was followed by tooth pain and two rounds of antibiotics for what the doctor originally thought was a sinus infection. Since then, the tooth pain is lessened, but I've had headaches, tingling in my hands and feet for a few minutes each day and now some tingling in my cheeks and chin. I'm wondering if this could possibly be MS, trigeminal neuralgia, or some sort of viral infection.

I've been to a neurologist who ordered an MRI and I'm waiting to hear the results. Can MS and trigeminal neuralgia be ruled out using an MRI? Are there blood tests that can rule out diseases of the nervous system? I've also heard that tingling and numbness can be a sign of stroke, but if the tingling is off and on and occurs on both sides of the body is stroke likely?
