I can appreciate your concern.
This definitely needs a medical checkup.
Yes, this could be pneumonia or lung
infection. There is a possibility that this is a lung infection but fever is usually associated with pneumonia, though not always. Other possibilities are bronchitis, or inflammation of the bronchus, and pleuritis, or inflammation of the pleura, the lining of the lung.
All these are possible complications from the viral
infection you have had.
Since the cough is so severe you are distinctly uncomfortable, it is best to show your doctor for this. Show as soon as possible.
Meanwhile some home treatment steps that you can take are:Fluids
: drink plenty of water. Humidifier
: use a humidifier in your room since drying of the sinuses can cause this. Warm compresses
: warm compresses on the sinus areas will give relief. Vit. C supplement
: 1000 mg Vit. C supplements daily (available OTC). N- Acetyl Cysteine
: this is a supplement available at natural food stores which helps drainage.Menthol steam inhalation
These steps will give you relief, but do show your doctor also.
Hope this shows you the way forward - wish you good health and a quick recovery.
