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. I experience muscle cramping in my legs and oesophagus spasms while eating. Does anyone else experience spasms of the oesophagus?

  2. My spasms also includes my toes. They twist & bend & cause me to lose my balance. My Hubby (a Naturalist) gave me a mix of Apple Cider vinegar, Honey with a bit of water/Apple Juice & the spasms leave almost immediately! Now, Peripheral Neuropathy.

  3. I have noticed unusual cramping in the backs of my thighs though it isn't frequent. I have been diagnosed with MG about a year ago but didn't realize leg cramps might be a symptom. Thought it was part of aging at 72. Double vision was my only symptom

    1. Here are some additional articles about cramping and MG: https://myasthenia-gravis.com/living/coping-with-muscle-cramping, https://myasthenia-gravis.com/living/shaking-spasms, https://myasthenia-gravis.com/living/leg-cramps-night. Certain treatments can also cause cramping as a side effect.
