Hi, im 18 years old 160 lbs (now 175 lbs) and have a fairly healthy lifestyle. For the past year, ive suffered with sharp shooting pains in my pelvis, and a sciatic like pain down my left buttock and leg. I frequently get pains in my lower back, and it always seem very tender and sore. My doctor told me i had sciatica in my left leg, and that it would go after 3 or 4 weeks on its own, but it hasnt, and im starting to think my symptoms are maybe that of a cyst/cysts on my ovary.
