Cramps in legs at night. Is this normal?

Hi, i am feeling cramps and pinches in my legs especially at night, twitching on knee caps, feets and cramps in lower back of the thighs, calf feels heavy and crampy. in morning arms at the joint, feels like stretch and bit burning type of sensation and twitch in forearms and fingers. Visiting the doctor in every 10 days, but the medication is not working i think. Calody-12 is the medicine going on at night from last 15 days. prior that some multivitamin and calcium + d3 medicine was strated. Is this normal? I took covisheild on 9th june 2021. And also i have headache issues, pulsing headache i metafor or diclogem for it. I am confused now. Morning breakfast is with milk and eggs and dry fruits. And i experience goosebumps also some times.
