The other Saturday 7/29, I felt a sensation on my throat like something got stucked on it. Did not worry much about it but during the following week it developed into a dry throat may be caused by me working outside under triple digit temperature sweating then going into an air conditioned room. Then last Saturday 8/5, I almost lost my voice and had blood on my plegm. I drunk hot tea with lemon and honey every 3 hours and by Sunday morning I could speak little better but not normally. This morning the top left side of my head is painfully sensitive to touch. The pain is like stabbing shooting that last a few seconds. What are these symptoms?
