I suspect i might have Multiple Schlorosis in its very early stages. Among other minor symptoms the most telling is my tendency to get muscle twitches that are rhythemic in very odd muscle groups. When this happens it sticks to a particular muscle group in a reptative way for weeks or months.
Here is a video of my chin twitching as an example.
@icedquinn i have always had potassium and magnesium problems. Thry are well supplemented though there may be an underlying issue.
Keep in mind though twitching a d cramps are very different.
