Hello, Thanks for your query.

Following measure will help- *Drink fluid-An electrolyte imbalance can be the cause of muscle spasms, so rehydrating with an electrolyte drink can help restore balance. *Stretch the affected muscle with a mild, static stretch. *Use ice to numb the pain in a cramp, reducing inflammation and allowing the muscle to relax. *Bring the affected muscle into a relaxed position and apply direct compression to the cramp. Dizziness could be due to high blood pressure. Get it evaluated by your physician. I do hope that you have found something helpful and I will be glad to answer any further query. Take care
