Is this MS?

[sandragail1]

My son was diagnosed with posterior uveitis 12 years ago, received 7 steroid injections and went into remission. No flare ups with eyes, but over the years had some upper respiratory infections which looked like possible sarcoid. That cleared up when he moved to Georgia 5 years ago. Two years ago he started having night sweats, vertigo, tremors, numbness, especially in the back of the head, lost feeling in hands once and had to pull over. Has had 3 MRI's (only 3 lesions it seems), positive spinal tap. Don't think it is related, but after LP he started feeling like he was going to black out. For the past couple of weeks, he cannot drive, and feels like he is going to faint when he walks even a block. Doctor put him on anti seizure medicine, and wants to start BG12 in the next couple weeks. My son was drinking a lot of alcohol since his college days (12 years ago) and he began smoking 5 years ago because he read that smokers don't get sarcoid. Does it sound like he has multiple sclerosis or something else? He also has an 8 mm nodule on his thyroid.

Does it sound like MS? Yes. Sarcoid is a mimic, but doesn't look like MS on an MRI. He has 3 lesions, and a positive lp.
The thyroid nodule could cause some of the symptoms, but none of the lesions or the positive LP. Likewise his drinking and smoking could cause some of the symptoms, but not the lesions and not a positive LP. He most likely has MS.

Has he seen a neurologist that treats MS patients? A specialist would run the true test (and you could even get second opinion). The doc will go through elimination of mimics etc. to reach a diagnosis.

Brain lesions can be caused by lots of stuff and a LP isn't a completely conclusive test.

Light headedness/fainting not something I hear of with MS.

Also, sudden loss of feeling in his hands would be unlike MS- especially if the feeling returned rapidly.

Some of the stuff you described sounds like an anxiety attack.

I'm not a doc, but for MS I would see a neurologist.
