Why days after shaving my legs (with a new razor) parts of my legs itch really bad? some parts itch so bad to the point of having red bumps & nearly bleeding. ive used the same body wash forever & ive tried benadryl cream, lotion & warm compresses?

Most likely a folliculitis, very common in women after shaving their legs, etc. Suggest that you shave after a bath and use an unscented shaving cream. Also, would be best if you shaved with the grain of the hair, usually downward. Even though it doesn't give you the best "shave", it would help avoid the rash. See your dermatologist for confirmation of this problem.
