Can you tell me anything about this? my husband keeps getting charlie horses in his right leg. and it still feels like it is cramped.

Blood flow: While this can occur from disturbances in the body's electrolytes, like potassium levels, it is also possible that there is compromised blood flow in the leg causing symptoms. It would be a great idea to see a vascular doctor, where simple tests like a doppler can assess blood flow in the vessels of that leg and see if it's ok. If not, then appropriate interventions can be discussed.

Need tests: Need to see the doctor , to check for vascular insufficiency or some other problem take an appointment to see his doctor.
