Hi, Thanks for using HCM.
Bodywide muscle twitching, burning left arm pain
, twitching in ears and throat and stiffness/feeling sore in left elbow and thumb may suggests calcium deficiency
. Hi get done your calcium and vit. D level once. If any deficiency take replacement tablet. But do regular exercise with plenty of fluids. Also take vitamin supplements. Consult your doctor for examination and management.
Hope I answered your question. Feel free to ask me if you have any further queries.
Wish you good health. Take care.
