Suggest Treatment For Vaginal Dryness And Loss Of Libido

I was shot in the upper right side of my head in 2002. I had no sex drive after that and vaginal dryness. My obgyn put me on Estrotest. It changed everything to normal!Then my family physican told me I no longer need to take it. I went of of it and my sex drive has went back to zero my hormones are up and down. headaches mood swings. I had a hystrectomy in 2001 partial hd both overies. In 2002 I had one overy removed due to cyst. I beleive my OB doctor put me on this for a purpose. He has now retired. Do I need to see a horemone doctor or a neaurologist?
