I have been to a neurologist and had a positive EMG and single fiber test. He suspects MG based on physical exam and nerve tests. The office called yesterday and told me my bloodwork was normal, so I am assuming that means negative. I am not taking any MG meds currently, but have developed new symptoms over the past few days. Just wanted to check and see if these sounded MG-like or if I needed to look elsewhere.
I woke up feeling ok, potted a few flowers outside and did a few mundane things around the house. Even before I suspected MG I had learned to pace myself and do a little, rest a little.
By afternoon, I was feeling incredibly weak. My hands had a slight tremor in them. As the weakness progressed, I found myself wondering how I was going to get from point A to point B. Then my lower lip seemed to be sagging a little so that my mouth was slightly agape. At the same time, there were little twitches in my lower face around my mouth and chin area. My face felt very weak and the twitches were similar to when you are upset and about to cry and your chin twitches when you are trying to hold it back. My neck was also very weak and I wanted to lay my head over on something to help hold it up.
I felt all weak and twitchy inside my upper body as well. I have had two major episodes like this, but I don't know if these symptoms are MG related or not. I drank a large cup of coffee, after which I began to feel somewhat better, but as evening came on I started feeling weaker again.
This morning I was fine again.

As a trial, today I did not take my thyroid meds. I have had some mild weakness and mild twitching, but nothing nearly as alarming as yesterday.
I have had two cups of coffee so far today. Afraid too stray to far from the coffee pot so I do not have a repeat of yesterday. I have a twitch in my left hand when I try to do things with it, such as scratch my face, etc.

The other possibility is that my thyroid med dose is too high. I had it checked a couple of weeks ago because I was having a pounding heart along with palpitations, but the test came back within normal limits. Maybe the test was skewed and this is just hyperthyroidism from too much thyroid.

I go back to see the neurologist next Thursday. Just hoping I don't get too bad over the long weekend.
What does everyone think? Is twitching a symptom of MG? I have not had this twitching before.
