Hi,
Thanks for writing your query.
Headaches can occur as a result of cold and fever. It can also be due to
sinusitis.
Single sided headaches are usually due to migraine attacks, which can be aggravated during cold and fever.
You should follow some precautions like :-
1. Don't miss a meal.
2. Have adequate sleep.
3. Avoid mental and physical stress.
4. Avoid smoking/alcohol, if any.
5. Drink lots of water daily.
You should get yourself clinically examined by your doctor.
Painkillers like Ibuprofen one tablet twice daily after meals along with an antacid like
Omeprazole 40 mg will be beneficial.
Steam inhalation will be helpful in case of
sinus headache.
Also get your eyes checked for
refraction by an Ophthalmologist.
I hope this is helpful to you.
Thanks.
