I am a 34 year old woman in New York and for the last 7 months, been having strange symptoms on and off. It started with my arms/legs tingling and then that went away. Then I noticed when eating, it felt like chewing was exaggerated and difficult. I'd be walking outside and out of nowhere, I'd feel a "wave" come over me and I'd feel weak and have to sit down. I'd also get dizzy when turning my head to look at times.
I saw a few Neuros and they ruled out MS. They said it could be anxiety, since I do have bad anxiety, and that could be the cause of the symptoms. I started meditating and taking anti-anxiety medicine and started feeling better. I was taking long walks again and all was well. I still had an appointment scheduled a month later for a Neuro-opthamologist so I decided to keep it just to see his opinion. He tested me for vestibular conditions and said everything was fine. He said "you have no issues from what I can tell. I can test you for Myasthenia Gravis but you don't present that at all and I highly doubt it's that, but let's check anyway".
The results started coming back in and they were negative. The last one was the MuSK antibody and that took about 2 weeks. I got a call from the doctor last week saying "Your MuSK antibody came back 2.81 and over 1.10 is considered positive." I was floored because I was not expecting it, nor was he.
I took the results to the 2 Neuros I was seeing for months and both of them are saying they can't see me having it. One of them even wrote a script for me to take the MuSK antibody test again because she is doubtful of the diagnosis.
That leaves me with questions such as is it possible my MuSK level is only slightly above the norm and not true positive? I really don't know the normal values people get when getting diagnosed so I don't know.
