My friend has a very bad cold, he can’t breath without difficulty. Nasal spray and decongestants don’t work.?

I’ve brought everything that I can and nothing helps him breath. He is a diabetic so he has to be careful of what he takes.

ok.. this may be a few things.. differential’s as follows (either way, if it’s that bad, go to ER, or doctor STAT): pneumonia, bronchitis, spinal (or other type) meningitis, strain of influenza b. He’ll need a pulmonary corticosteroid and/or Pure oxygen for the breathing.. but medicine will help for long term..
