My fingers start to lock on one or both hands
while I'm eating at a restaurant. The cramps last as long as 15 or 20 minutes. Are there certain
foods or chemicals that cause this? I thought maybe it's sugar or food preservatives that cause this symptom. I know that when I eat or drink too much sugar I get leg cramps several hours later. I usually eat salads, soup, fruit. This has been happening for a few years. I am in my early 70s. I have acid reflux and high blood pressure.
