HI! I'm at my office and am getting over a cold (day 6)....chest congestion, minor sinus problems. Went to my dr. yesterday and received a cortisone injection plus antibiotics and mucinex DMX. I'm not 100% by any means, but all of a sudden, I smelled a curious smell...not unlike something burning, but not exactly. My lips/tongue had a slight tingling sensation and I felt lightheaded. Still a little lightheaded, but the other symptoms seem to be gone. Any thoughts? It was very curious.
