Are my symptoms neurological? should I be worried

Patient: Ave a very inactive life style. I’m 20 years old female. Poor diet, anemic.and only 98lbs I sometimes get twitching in my eye lids and what I guess are muscle spasms in my calfs. My calves also feel a bit tight when I’m doing physical activity like I’m about to get a Charley horse so I get scared and sit down. Lately I’ve started experienced toe twitches. It seems to only be in my right foot while resting. My muscles also seem a bit weak after carrying grocery bags. I. Afraid I have a neurological disease and I’ve been searching the internet all night. Do you have any idea what it could be?

Symptoms: Muscle weakness soreness and twitching/spasm
