For the past few months, my feet, toes, and calves have been partly numb and I've had tingling and buzzing nerve pain there. Over the past few weeks it's gotten much worse. All of my symptoms persisted and my legs got really stiff and twitchy. My balance and muscle control has been affected too. I have a hard time walking. I've tripped and fallen on multiple occasions, and I can't walk up stairs unless I go very, very slow, and use the rail to pull myself up the stairs. I'm constantly stepping all over the place like I can't control my legs and I have to hold onto a wall or desk in order to stand still without swaying or falling over. At the beginning of my symptoms I assumed it was a b12 issue and supplemented for a few months but when that didn't help I began to suspect MS.
Suspecting that I have MS, I went to the doctor and had bloodwork done. She had everything tested, over 20 individual tests. My b12 levels were in the high normal range (900) and everything else was perfect except my thyroid stimulating hormone. It was quite a bit above where it should be(11). I found this strange because other than being tired and cranky lately I don't have any other typical hypothyroid symptoms. My doctor prescribed me some thyroid meds and I have a phone appointment with her tomorrow.
Does my hypothyroidism explain my neurological symptoms, or are they caused by something else? Should I still be concerned about MS?
I'm 23 F, white, Northern California, overweight but not obese, no other medical diagnoses or prescriptions other than hypothyroid.
