Can mold give you a headache and stiff neck?

Yes : Typically low mold exposure results in allergy like symptoms: itching, redness, sneezing, watery eyes and headaches. If the exposure goes for a longer time and or you are exposed to high levels of mold, then other symptoms may result such as joint pains, breathing disorders, nose bleeds, chronic fatigue etc. Signs of stiff neck suggest possible meningitis and needs to be evaluated and treated.
