welcome to healthcare magic..
wel from your above depicted symptoms.. itz quite clear that the pains which you are having is not due to ovarian cyst
because the pains from ovarian cyst may be radiated to back , hip and groin but not upto the calf area... it wil radiated only only above the knee...
and as u said bulging discs and sciatica
runs in your family its quite likely that u may be having the same too..
i suggest you to go soon to a nearby orthopaedician and get it examined, on examination it wil be clear and confirmed by proper radiological investigations... till then dont lift heavy objects esp while bading forward and take rest..
i hope i solved ur query..
i wish u get well soon..:)
