As you rightly said that you had an attack of sinusitis
which was probably triggered by all the smoke and fumes. The sinusitis has now become chronic ie the infection is still persisiting but in lower intensity. I hope the antibiotics that you took were adequate in dosage and duration. You may repeat the course and take megapen or azithral
for at least 5 to 7 days. Continue doing steam inhalation and some deep breathing exercises. For your aches and pains take a pain killer. Do you have any kind of allergy? Take an anti allergic like cetrizine/loratadine
and a monteleukast like montair. I`m sure this will help.
