I would try a free clinic such as Planned Parenthood. You can find an add for them in the Yellow Pages. They will also give you free meds. My friend had the same problem and her Dr. put her on birth control to lesson the pain and extreme need to change every half an hour. You can also buy health insurance from Blue Cross Blue Shield on a monthly basis. The cost is not bad and it will cover you in an emergency such as a broken leg. My daughter had to do that for six months until her insurance from work kicked in. I think it cost her about $60.00 a month. Good luck.
