Started having severe leg, foot cramps with burning sensation. Hurts to walk OR rest. Legs keep going numb...should I be worried????

You should be. seeking a medical evaluation, is what you should be. I don't know what you have, but if you're not sure whether you should be worried, then you should be at least concerned. Could be minor, could be serious, but you won't find out sitting in front of a computer. An actual live doctor needs to lay actual hands on you in an actual brick-and-mortar office.
Y R U Waiting???? You need to be seen, and right soon, to get to reason of your complaints. The symptoms are in no way normal and could be of some significance. If the symptoms are escalating then go to the urgent care. Otherwise, tomorrow see your physician.
