Hi, My fiance and I were helping his family paint their new apartment and refinish their front door yesterday. He was exposed to the turpentine fumes used for the varnish (probably about 20mns). No one else felt any side effects but he was the one working on the door. About an hour later (and to this point), he was complaining of throat pain and a headache. Is there anything we can do to soothe him and help him get better quicker? Thank you
