Dr. David :

This is Dr. David

Dr. David :

this could be due to electrolyte imbalances in your blood stream.

Dr. David :

like not enough magnesium or abnormalities of your potassium levels.

Dr. David :

or it could be due to a pinched nerve in your elbow or spinal cord

Dr. David :

or something else like a neurological disorder like parkinsons disease

Dr. David :

how long has this been going on?

Dr. David :

have you had blood work to check your electrolyte levels?

Dr. David :

hello?

Customer:

Thank you. I have had comprehensive blood tests recently - for liver, kidney function, psa, glucose level as part of the health check given by my new GP and all seemed well. I can ask for an electrolyte one if it hasn't been already covered. The symptom has been with me for several years but has not occurred frequwntly enough to be really worrying.

Dr. David :

I think you need to be referred to a neurologist if your GP is not helping.

Dr. David :

it sounds like you have already had most of your electrolytes checked.

Dr. David :

ask to have your magnesium levels checked.

Dr. David :

magnesium is needed to help muscles relax.

Dr. David :

you could have an occasional pinched nerve in your elbow which might be causing your symptoms.

Dr. David :

sometimes muscles cramps in the hand can cause this occasional contraction

Dr. David :

and occasional low potassium levels in the blood can sometimes cause it.

Dr. David :

you might want to try eating more bananas and orange juice which have more potassium in them and see if that helps next time.

Dr. David :

do you have other questions?

Dr. David :

hello?

Customer:

Thank you. I will do those things.

Customer:

Frank

Dr. David :

you are welcome
