I have itching/burning after shaving my legs, no matter what razrs or shaving cream I use. What can I do to prevent this? Out of options!

First try. Never shave dry, always use a high quality gel and clean fresh razor and only shave in the direction of hair growth. You may also apply an over the counter Hydrocortisone cream after shaving. If this does not work see your dermatologist for prescription strength options.
