I've experienced head tingling that comes and goes, also cold sensations(feeling colder than normal) and numbness sensation(but I can still feel) and chest tightness. My doctor pretty much thinks I'm crazy. He prescribed me propranolol and he said the symptoms should go away within two weeks. I suffer from anxiety already,I have a fear of going out and people watching me. So I stay in the house all day on the computer. Is this anxiety playing tricks on my mind? The more I search these symptoms the more I'm scared I have MS.
