Hi, sorry to hear you are having problems and welcome to the group.
Your symptoms do sound like MG, although there are many problems that can have similar symptoms.
Usually we go to our MD and have a basic ACHR blood test. That picks up most of the folks with MG, but not all of them by seeing if we have bad antibodies in our blood. Get your regular doctor to order the test and visit a neurologist and tell the doctor about your symptoms.
I think, for most of us, MG is different from other problems in that although we have strength, we tire very quickly of the things we are trying to do. My neuro would have me grip his hands and pull against his pulling. I could do fine for a short time, but in less than a minute, my strength was gone and he could easily overpower me.
It takes time to get a neuro appointment, so ask your regular doctor to get a blood test now.
Good Luck
Russ

Hi
Yes I agree with Russ, your symptoms do sound like possible mg.
I noticed similar weakness to you at first and then my vision started to double and speech slurred.
My reg doctor did the ACHR blood tests to confirm mg and then I went on to my neuro.
So yeah get that blood test.
Good luck to you and you can get better , I was very weak less than a year ago but now I'm doing much better. There is hope!

As an update, I developed double vision about two months ago, and I finally got an appointment with an MG expert in my city. He was able to confirm the double vision objectively during our first appointment, and he immediately gave me a trial prescription for Mestinon.

I started taking the Mestinon last week. For the first few days, I was taking one pill per day, just in the evening, and I did see improvement in the eye symptoms. But yesterday was the first day that I took it toward the end of an active day, while I was still out and about. And about 30 minutes after taking the pill, the heaviness in my legs that I had come to take for granted, and that had been making me feel as if I couldn't bear to walk another step after a "long" day (walk to the train station, dinner with husband, one hour browsing in a bookstore, and strolling after that), simply evaporated and I felt like a new woman. I felt as if I could easily go for a jog.

I actually started crying on the way home, while I was walking with that new lightness in my step, because I realized just how much and how needlessly I had been suffering for so many months. It was simply magical to feel that I finally have a chance at getting my life back, and also maybe a bit crushing to understand that this is really happening, that yet another incurable chronic disease has pushed its way into my life and is here to stay.

So glad that this group exists, and hope to contribute as much as you all have already contributed to my understanding of what life as an MG patient will be like. Best wishes and cheers to all!

OH! And I will add that I got not one, but TWO separate psych referrals on my road to this diagnosis. It was so hard to stand my ground and insist that someone actually bother to investigate my symptoms before kicking me down the garbage chute, but it was absolutely worth it. The malpractice and laziness when it comes to these challenging diagnoses is simply stunning, and it's so important to call it out -- and what's to lose, if we are destined to get a psych referral anyway? ;)

Mestinon is like a miracle drug for most of us with MG. However, it treats the symptoms and not the cause (bad antibodies). I took about 6-8 of those per day when I was at my worst (60mg pills) so I could function. But my MG kept getting worse and so I had to begin an immune suppression treatment (prednisone) that treated the cause of MG.
Many of us have similar stories -- I too was diagnosed as depressed and "out of shape" and sort of believed it before finally finding out MG.
Good Luck
Russ
