What do shaky hands and numb toes while walking point to?

Hi doctor,

I had my first appointment with a neurologist this week. I am a 21 year old student. The past several years I have been dealing with shaky hands, worse on my left side, that has continuously gotten worse. I also have hypothyroidism and had hoped that as my thyroid balanced out, the shaking would decrease, but it has only gotten worse and now the shaking often moves up my arms and makes it very difficult to write or work. Within the past year, I have noticed that some of my toes go numb while walking and can stay numb for several days. Recently I have noticed numbness in my right arm at times. My neurologist first thought it could be from stress, but then proceeded to run through a series of tests where he mentioned that the reflexes in my feet were very uncommon and that my pupils also were not working the way it should. He asked about any back pain, I told him I struggle with that as well. He then did a test where I would touch my nose then his finger, I could do it on my right side, but missed every time on the left. He ended up taking quite a bit of blood and asked to get magnetic resonance imaging (MRI) of head and cervical spine this week. He did mention that this could be serious and heavy, but not much else. Currently I am on Levothyroxine. I am starting to get nervous and wanted to see if anyone had any input or ideas about possibilities or conditions that could be wrong with me? Thank you so much.

Hello doctor,

Thank you for your response. No, I have not been hospitalized for vomiting. Yes, I sometimes struggle with my vision looking blurry, and last week when I visited my neurologist, he was a little concerned with the eye test results. In the past few months I have noticed numbness in some of my toes, occasional tingling in legs. I do not struggle to hold things. Sometimes I just cannot use the object because my hands can be so shaky. No I do not have any cervical pain but have back pain. When I found out about my thyroid problem, I had gained quite a bit of weight suddenly. It has taken about two and a half years to get my thyroid balanced out, but mid of this year I lost about 40 pounds. I assumed it was my thyroid getting back in check, weight is still dropping off slowly. I do have a hard time with my memory. No other neurological issues. Thank you again for your help.
