How Mastocytosis Might Present Itself 

Mastocytosis can manifest in various ways, depending on the organs and tissues affected by the excess mast cells. Common symptoms include skin lesions, itching, flushing, abdominal pain, diarrhea, nausea, vomiting, bone pain, and fatigue. In severe cases, mastocytosis can lead to life-threatening allergic reactions known as anaphylaxis. It’s important to note that symptoms may vary from person to person, and some individuals may experience mild symptoms while others may have more severe manifestations.
