I am Dr.Amita and it would be a pleasure assisting you today.
If the earlier vomitus only had traces of blood with following vomitus clear you do not need to worry about it and you do not need to do anything for that.You do need to get the infection and repeated episodes of vomiting evaluated and treated.
This can be due to damage to lining of food pipe sustained by retching
If there is an active infection with pus drainage at the toe you may need oral antibiotics for optimal treatment as antibiotic cream may not suffice.
You will need to get yourself examined for traces of blood in case you have a history of gastritis or you have had an episode of similar bleeding before this episode.
