Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns.
As per your complain swelling on one side of face along with numbness and
dizziness can be due to
sinus infection and I would suggest you to consult an Otolaryngologist and get evaluated and he can do a clinical evaluation and along with it he can advise you an MRI or PNS View X ray of sinuses to confirm the cause..
In case if
sinusitis is confirmed he can advise you to take a course of antibiotics like
Levofloxacin, anti-inflammatory painkiller like Advil, decongestants like Pseudoephadrine, steam inhalations, saline
nasal irrigation and steroid nasal sprays..
He can also advise you decongestant nasal sprays, warm compresses over the face and also avoid air conditions atmosphere..
He can also advise you to avoid chilled foods..
Hope this information helps..
Thanks and regards.
