I have a bullseye rash but no sign of a tick could the bite have been a chigger or ant?

Prophylaxis: If you live in an area that has ticks, you may be better off taking prophylactic treatment for Lyme disease. It would be prudent to see your doctor for an evaluation. 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, if you are under 27 years of age.
