Thanks for writing your query.
According to the symptoms described by you, there might be a possibility that you are allergic to the paint fumes. You are also having flu
. This has resulted in aggravation of the symptoms.
It will be advisable that you get yourself examined by a medical proffessional and take antiallergic like Fenofexadine
120 mg, one tablet daily for 3 -5 days under medical supervision.
I hope this is of help to you.
