Mast cells are really complex. From what I understand they can selectively release their mediators (for example histamine when you have allergies). Or they can completely degranulate and release histamine, prostaglandins, heparin, etc. and can cause a multitude of symptoms beyond allergies.
In Mastocytosis, which is rare, you have an over-proliferation of mast cells as well as aberrant activation driven by a few rare gene mutuations. In Mast Cell Activation Syndrome, which is believed to be much more common, there is not an over-proliferation of cells, but the normal number of mast cells you do have are easily activated. The don't yet know why.
Here's one list of symptoms that are associated with both Mastocytosis or MCAS. Of course many of these symptoms you'd associate with allergies, but others are related to the other mediators such as heparin which can lead to skin lesions, orthostatic intolerance, etc. If you have a good number of these symptoms, you are certainly experiencing more than allergies (even bad allergies) and can suspect Mastocytosis or MCAS.
