Based on the symptoms you described, it's possible that you may be experiencing an allergic reaction to certain foods. An allergic reaction occurs when your immune system overreacts to a substance (allergen) that it perceives as harmful. When you consume a food that you're allergic to, your immune system produces antibodies called immunoglobulin E (IgE) which bind to cells called mast cells. These mast cells then release histamine and other inflammatory mediators, leading to symptoms such as burning, itching, bruising, and swelling in the mouth.

In your case, the foods you mentioned (Pb plus Nutella Pizza, 2 M and ms 1 em everyday Bread roo) could be the potential allergens triggering the allergic reaction. It's important to note that food allergies can develop over time, and even if you've consumed these foods without any problems in the past, it's still possible to develop an allergy later on.

To confirm if you have a food allergy, it's best to consult with an allergist or immunologist. They can perform allergy tests, such as skin prick tests or blood tests, to determine which specific foods you may be allergic to. Once the allergens are identified, it's crucial to strictly avoid them in your diet to prevent future allergic reactions.

In the meantime, it's recommended to carry an epinephrine auto-injector (EpiPen or similar) in case of a severe allergic reaction (anaphylaxis). Anaphylaxis is a life-threatening condition that requires immediate medical attention. Symptoms of anaphylaxis can include difficulty breathing, swelling of the face, throat, or tongue, rapid pulse, dizziness, or loss of consciousness. If you experience any of these symptoms, use your EpiPen and seek emergency medical assistance immediately.
