I wanted to pass on something that happened to me recently. Since September my erythromelalgia has been terrible - flares every day, carrying ice packs wherever I go. Then my neurologist told me to come off of amlodipine becuase it has a high interaction with myasthenia gravis. Well, that was a week ago and since then I have barely had any erythromelalgia symptoms as well! I did some reading and did find that that type of blood pressure medicine can aggravate that as well. Just wanted to pass this along in case anyone else has been experiencing the same.
