Hello and welcome to MedHelp's forums. We suggest you speak to your doctor about this. You may have an allergy as hives is the most common sign of that. We'd suggest you do not eat eggs until cleared to do so by your doctor. I'm not sure if the sores in your mouth are related to hives but regardless, if they don't happen when you stop eating eggs, that is a good indicator that eggs are not good for your diet. https://www.mayoclinic.org/diseases-conditions/egg-allergy/symptoms-causes/syc-20372115
Hello~I would appear to me that you are allergic to eggs or what they are feeding the chickens that are showing in the eggs. I would either stop eating them or buy organic eggs directly from the farmer and make sure they don't feed them any additives. I am allergic to eggs, but if I eat organic, farm fresh eggs, I don't get any type of tummy ache or any reaction.
