Hi john27, welcome to the board!
How long have you been having these symptoms? Do you have other symptoms? Have you seen a doctor? Magnesium deficiency can be one reason for muscle cramps, but there can be others.
Lyme disease is a multi-system bacterial infection caused from the bite of an infected tick. Many people are bitten by ticks without knowing it. They are tiny, they often go in hard-to-see places, and they inject a numbing agent so you cannot feel them on you.
Below is a Lyme symptom list. You can have any combination of symptoms.
When Lyme disease is a possibility, it is very important to see a knowledgeable doctor. Many doctors do not understand Lyme and treat with outdated protocols. No test is completely reliable, and results can vary by lab. Besides Lyme, ticks can also transmit several co-infections including Babesiosis, two types of Ehrlichiosis (HME & HGE), Bartonella, and Mycoplasma. Many people who have Lyme are co-infected.
If you think this is a possibility and if you need a doctor recommendation, let us know. I hope you can get relief soon.
