It is critical that you inform your doctor and anesthesiologist before undergoing anesthesia. As part of your anesthetic, you may be given drugs that do not cause malignant hyperthermia.
Treatments:
Medication - The response is treated with dantrolene, a medication that inhibits the release of calcium into muscles. Other drugs may be used to rectify abnormalities with the chemical equilibrium of the body, which is a metabolic imbalance, and to treat consequences.
Cooling of the body - To assist lower body temperature, ice packs, cooling blankets, a fan with a cold mist, and cooled intravenous (IV) fluids may be utilized.
Assistive care - You may need to stay in critical care for a day or two to have your temperature, blood pressure, heart rate, breathing, and reaction to therapy monitored. Several lab tests will be performed on a regular basis to determine the amount of any muscle breakdown and potential renal injury. A hospital stay is frequently required until lab test results begin to return to normal.
It depends on what causing it. the only thing I can say is to drink plenty of fluids but I would recommend to go see a doctor, if you are unsure or worried.
