What are the frequent symptoms of a mast cell activation disorder or mastocytosis?

The frequent symptoms of a mast cell activation disorder or mastocytosis are generally of an inflammatory nature and multisystemic.  The various manifestation of inflammation are often unusual or atypical as well.

Dr. Theoharides categorizes the symptoms this way:

Orophayngeal: burning pain, aphthae

Dermatologic: flushing, pruritus, urticaria pigmentosa, angioedema, dermatographism (sometimes)

Respiratory: wheezing, sore throat

Cardiovascular: chest pain, hypotension, tachycardia

Gastrointestinal: abdominal pain, nausea, vomiting, diarrhea, bloating, malabsorption, esophagitis

Naso-ocular: nasal stuffiness, pruritus

Neurologic: headache, memory and concentration difficulties/brain fog, paresthesia, peripheral neuropathy

Muscoskeletal: bone/muscle pain, degenerative disc disease, osteoporosis/osteopenia

Systemic: anaphylaxis, fatigue

Dr. Afrin recently categorized the symptoms as follows:

Abdominal: abdominal pain, intestinal cramping and bloating, diarrhea and/or obstipation, nausea, non-cardiac chest pain, Helicobacter pylori-negative gastritis, malabsorption

Respiratory: cough, asthma-like symptoms, dyspnea, rhinitis, sinusitis
