Hi, Was trying to go to bed late last night when had the sudden urge to throw up. Ran to toilet threw up then went back to bed. 10-20 mins later got the same feeling, was throwing up mostly stomach acid this time, very bitter taste in mouth. But last time throwing up was just a little bit of blood. Was bright red. Not a lot but enough to possibly be concerned about. Didn’t feel dizzy or anything just tired. So ended up going back to bed, and wasn’t feeling nauseous at all. Woke up, throat a little sore and been feeling kinda tired today. Also no visible blood in stool. But no other symptoms, no pain. Should I still go to the er? Or should I not be concerned about this. Also want to add I was feeling hungover and very anxious all of yesterday, but not nauseous until very late.
