These approaches should be discussed with your doctor. It is also possible that the increased tryptase itself causes the symptoms without requiring mast cells to be activated, or it could cause an abnormally increased response to otherwise normal mast cell activation, which might explain why so many patients respond to medications that target mast cells and substances released by mast cells.
