The radiating pain
from pelvis to the legs suggests involvement of nerves either in pelvic region or in the lower back. Since you are getting excessive facial hair
, one would suspect problems related to ovary. Ovaries are very muck close to the nerves in pelvis and so pain could also be related to that. Frequent urination
may suggest urinary infection. You should consult a gynecologist and get evaluated for all these. They will ask for a scan of the pelvis and urine tests.
