Hello and hope you are doing well.
Allergic reactions can show a waxing and waning phenomenon. They can improve or worsen with time. Also it is possible to develop new allergies, you could develop new allergic reactions to food or other substances. You will only have to closely monitor. If you haven't undergone formal allergy testing, that might be beneficial. Under a doctor's supervision, foods that have caused allergies in the past can sometimes be added slowly back into the diet.
Hope this helped and do keep us posted.
Also is it just me or is it bizaar that this only happens on the left side of my body???
How could I be completely fine for 2 years eating and drinking what I wanted and then all of the sudden I have another reaction. Like I said I haven't eaten or drank anything out of the ordinary???
I would stop dairy and get tested for gluten problems too. I have no allergies since figuring out my food issues.
