I Have Been Taking Raloxifene Hydorchloride For A Month And

I have been taking raloxifene hydorchloride for a month and a half. I have noticed an increase in leg cramps but the worse symptom (?) is my scalp has been itching a lot. Almost as if mosquitoes were biting. It is very hard not to scratch and when I do, my scalp burns. It is not constant but seems to come and go. Could this be a symptom or not?
