Could I've had meningitis and not notice it? Had (still do) a stiff neck, headache (only when I shook my head), muscle pulling and twitching. Help

May be. Viral meningitis may produce relatively mild symptoms, however, you should see a doctor to get checked out. You may consult this site for information: https://www.cdc.gov/meningitis/viral.html For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex. Get HPV vaccine.
