Hello dr i keep smelling burning plastic and it gives me a terrible headache. No one else can smell it. I have many severe health problems and am terminally ill with heart failure. Is this related. I asso have my 3rd dvt in left leg i am on Apixabam but this last week my led in very painful and i have a dint in my calf but no serious swelling. I struggle with breathing but unsure if thats due to my heart condition only.
