Yes, some of the symptoms could be due to
mold allergy. There are various skin tests
and a blood test called RAST which can detect
mold allergy. You could also be having a systemic fungal infection.
However there are other causes too like diabetes, hypothyroidism, polyarteritis nodosa that should also be looked into. Anemia and low blood sugar too can be a cause for your symptoms.
Hope this helps. You must consult an allergy specialist and an internal medicine specialist.
