Started getting random cramping in my feet/hands a few days ago Lots of muscle twitches as well. Not severe, but mild cramps. What can cause this?

Cramping. in the feet and hands can be a sign of dehydration. If it has continued and is unresolved you need to be seen by your provider for an exam, lab work and a proper diagnosis. This can also be an initial symptom of a neuromuscular issue. Get lots of fluids and be sure to eat healthy!
Electrolyte imbalanc. You should have labs drawn for potassium, magnesium and calcium. Muscle enzymes should checked as well. If your symptoms persist, a neurologist should be consulted.
