My mom is 47 and on premarin because she had a full hysterectomy a long time ago. Lately, she has been getting two really sharp pains at the same time. One of them is close to where her leg turns into her labia and the other one is on the inside of the middle of her calf. It doesn't last very long and it really seems to catch her off guard. Anyone have any idea what this could be? It seems like one of those things a doc can't really examine because it doesn't show.
