over the last month I have had severe burning pain in my right leg, with numbness and heaviyness in my foot. since this started I now have severe pain in my hip so much so that I can not even put on pants because it causes pain, my left foot has shooting pains in it and my upper back hurts when I breathe. I have some other symptoms that I don't believe are related such as bladder urgency, diarirrhea, migraine head aches and blurred vision. My doctors have referred me to a neurologist, but the pain is getting worse and worse. I don't know if I should go to the ER or not
