Ovarian cyst sometimes doesn't need to be treated if the size is very small. In some cases they just diminish and disappear without any management. If it is bothering you, the only choice for you is to remove it during surgery.
For curing PID you may choose Fuyan Pill.
Fuyan Pill as my patented herbal formula, has been used in my clinic here in China since years, it has already cured thousands of PID sufferers. You may have a try as well. Improvement can be seen after one month treatment and symptoms can be cleared up after three to four months medication.
