Hello. I have some sciatica, which I'm guessing is caused by some piriforitis but will be going to the doctor soon about that. But sciatica runs down the back of the leg and into the foot and I'm also having razorburn-like pain from the inside of the top of both thighs down to the top of both knees. Any ideas as to whether or not this could also be caused by piriforitis or maybe something else? I'm also going to a doctor to help determine whether or not the pudendal nerve is involved. This is a nerve not too many people are familiar with however, if anyone out there can give any insights into what may be causing this pain please let me know. Thank you very much.
