My friend has experienced severe dizziness for the last year.  A doctor asked him if he had any bug bites.  It so happened that around a year ago, approx. 4-5 weeks after a severe allergic reaction to a bug bite is when his dizziness started.  Can you explain more about this issue?
An allergic reaction occurs when the immune system overreacts to an allergen. So when the insect bit your friend, he developed hypersensitive reactive reaction. Now as his body is fighting against that foreign antigen, whicChatDoctore via the bite makes him present with a symptom like dizziness, which means that insect secretion is like a venom to the body causing toxic reaction involving the immune system. I HOPE I AM ABLE TO MAKE YOU UNDERSTAND.TAKE CARE
