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. Have MG and get cramps after tapping my feet to music for long periods. Best solution is a spray under the tongue of CRAMP FIX or Cramp Ease. Contains vinegar, sugar, salt, potassium, calcium and magnesium. Works in a minute. Graham from Australia.

      1. glad you have found what is helpful for you. We always recommend reaching out to one's physician before adding anything new. As magnesium can make MG symptoms worse. I shared an article on this here - https://myasthenia-gravis.com/clinical/magnesium-sulfate. Wishing you continued relief. Kindly, Jessica (Team Member)
