Low potassium levels?
I have been experiencing muscle cramps in my arms and left achilles tendon.. And sometimes my heart pounds hard. Yes I’ve had an EKG and a halter monitor and things came back fine. I have an appt today. Also Once a month for a few days the crams and heart beat are intense. Then goes back to normal very fast. I was wondering if it sounds like low potassium?
it can be sodium potassium or calcium also sedentory lifestyle like sitting with computers or even water and salt depletion from over activity as in sports men, certain things like coffee or carbonated drinks also can trigger it.
