I've been struggling with breathing issues for the past couple of months and my doctor mentioned it's due to allergies from things like apple, banana, milk, and even coconut. He prescribed me something called a histoglob injection, with a schedule of weekly injections, then a break, and then more weekly doses. I'm really concerned because this is all new to me, and I'm not sure about the dosage or possible side effects. Can you explain what I might experience with this injection?
