Muscle cramping

I haven't been diagnosed with MG but my doctors and I are believe it is likely causing my symptoms, notably double vision and extreme muscle fatigue that varies throughout the day. AcHR and MuSK were both negative but I asked for some additional tests before we rule out MG.

My main question revolves around muscle cramping. I'm addition to profound muscle weakness at times, I have intense muscle cramping (mostly in the legs but also sometimes in the arms). It feels like my muscles are trying to contort in an unnatural way and I am unable to relax them. Afterwards they will be so sore and it feels like I did a really intense workout. If I try to use that muscle after it will burn and become numb and weak within minutes.

My muscles ache reflexes are also very sensitive. A gentle touch can cause then to spasm.

Does anyone with MG experience this? Or should I be considering different diseases?

  1. Fingers spasm when the a/c turns on in my living room. My recliner is fairly close to it. So I bury my hands under the blanked to warm them up and stop the spasms.

    1. Yes. Cramps. Just in morning, about to wake up. Calf muscles. Just shake my legs, goes away. Whole episode, maybe a minute.

      1. Yes
