Been on Prostrap for 4 months (3 single doses and more recently a 3 month dose). Only just been prescrbed the add back Tibolone. Was pain free after first month of Prostrap but with Tibolone I am now having pelvic pain. Doctor said Tibolone would help prevent osteoporosis etc but eostrogen would not affect ovaries having it as an add back. Anyone else had these symptons? It's very painful today and I am miserable having been pain free for 3 months!
