Hi, Welcome to Health care magic forum. As you are having the IUD, more than 3 years, it is to be removed, and changed with the new one. It may be the infection, due to the IUD, or may be an independant infection. I advise you to consult a gynecologist for diagnosis and treatment. Take more of green leafy vegetables, pulses, sprouts,and protein rich foods to hasten the recovery. Wishing for a quick and complete recovery. Thank you.
