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. Every night and when I lay down in the afternoon.

    1. Yes but my doctors claim it it a Mestinon reaction. Who do you believe?

      1. Excessive standing and not hydrating properly, gives me leg cramps.Immediate relief comes from mustard packets. Once cramps begin. I eat a spoonful or packet of regular yellow mustard. 1-2 minutes, the cramps subside and I can resume normal sitting.

        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.
