Im just wandering if anyone has had any experience of leg pain while taking clomid. I've been on it 100mg day 2 to 6 now for 3 months. At the end of Jan I flew to boston from Ireland for a vacation. I thought i had pulled a muscle from all of the walking! For the past five weeks my leg has felt as though its about to go into cramp at any minute and I now have a big varocise vain at the back of my knee that i didnt have until recently. The pain is right at the back of my knee and doesnt stop at all. Im just wondering if anyone else has had anything like this? Or am I just a freak.
