I have cold for a log time and i feel fever with it as well what should i do?

Sinus: This sounds like a sinus infection and antibiotics may be needed. You can also try to use a nasal rinse, or take decongestants, or use nasal sprays.

Cold: Cold are caused by viruses and unlike bacterial infection antibiotics don't work for viral infections. You can take regular pain killers to help you feel better. If your nose is blocked you can use over the counter alien nose drops or striven nose drops ( only for short duration- long term use causes side affects ). Drink hot drinks like soups and rest. If any new symptoms arise then see doctor.
