Hi Lit Love. I am just starting on ketamine oral - tonight in fact - and figure that would be a good one to be taking when the biopsy is done and after. I heard it is painful. I plan to call my PM doc Monday. I am in menopause and have been bleeding recently. They did an ultrasound and found that I have a thickened lining. My female doc wants the biopsy asap. It would be horrible to have burning pain reside in the female areas.
