Hi Ohio. The cardio may refer you to her general practitioner for that, but do mention it. I have trouble with leg cramps. I am given a prescription for quinine sulfate. Do not confuse this with quinadine which is something entirely different. If your daughter doesn't mind bitter tastes, in the meantime, she might get some relief from plain old Tonic Water. It has a small amount of quinine in it. It is used to mix alcoholic drinks, as in Gin and Tonic,but has NO alcohol in it. Not Soda water. You want Tonic water. I ususally squeeze a little fresh lime into mine. I drink it all the time. I used to get charlie horses as a child. Both my cardio and my GP said they were not related to the aortic stenosis, but they didn't come back until my valve started worsening. Also, though, I began menopause, so again, perhaps she is having some hormonal changes bringing these on.
The quinine sulfate REALLY helps me so definitely mention it to the doctor.
Good luck to her!
