Hi, Had a sore throat for a èw days and went home from work half day feeling a bit unwell -nothing specific, just generally unwel, tired with the sore throat, no fever or other symptoms. Got home and started vomiting. Vomited for 2 days. At firrt was normal bile colour, towards end it was dark grey, almost black. 24hrs prior to vomiting had not eaten much due to sore throat. Any info much appreciated. Will go to my gp next week.
