I am a 56yr old white women. I had a sore throat 2 days ago, also servere pain in upper left abdominal area. Yesterday, I vomitied blood with like blood clots, only about 1 teaspsoon in size. I thought it was from the sore throat, most likely being so sore that it was raw...my doctor had put me on a zpack since I have had some medical training... but then I was tired this whole time, and feverish...I started to vomit more...so I just stayed on the couch which is my bed,,,and today am afraid to take 3 day of zpack for fear of vomiting again? Should I? am at a friends house right now and drinking coffee and have takin all my high BP meds and seem to still have small sore throat...?
