Hi and welcome to Healthcare Magic. Thanks for your question...
Phobia is a type of anxiety
disorder where there is excessive and irrational fear of something, leading to avoidance of that fearful stimulus / object. In your case, the appearance of your symptoms seem to be corelating with the incident of closely obseving blood / injury and so is likely to have been the cause of your nausea
. But still, in order to technically qualify for a diagnosis of blood phobia
, you need to have had persistent such aversion to blood / injury, along with avoidance of such situations (...which you say is absent). It could be that the straining of your eyes to closely observe / clean his wounds along with fatigue
may have caused the nausea. However, if these symptoms keep repeating again in similar situations, then it is more likely that you have a phobia.
Wish you all the best.
