I don't know if it's something in my house (my puppy tears apart everything and hides stuff) but I'm smelling vinegar quite strongly. Should I be worried? I have been sick for awhile now with some URI. I also have health problems such as hypothyroidism, Crohn's disease, asthma, psoriasis, and arthritis. I'm on immunosuppressant medication, including IV therapy. I'm a 26 year old female. I don't know if this smell is health related but it's unpleasant and hasn't gone away.
