I've been dealing with a cyst on my left ovary, and initially, it was 4cm but now it's shrunk to 3cm. Occasionally, I get these sharp abdominal pains, which are pretty concerning. I also have my periods every 20 to 22 days, but they bring on intense pain in my legs, thighs, and lower left back. My doctor hasn't prescribed any meds for the cyst yet, and I'm wondering if that's something I should be worried about. Is it crucial to get this cyst treated, or will it just resolve on its own? Could it cause issues down the road?
