HI, thanks for using healthcare magic
It sounds like a viral illness particularly either the common cold
or the flu virus. In the flu , however, the symptoms are usually more severe with significant joint and muscle pain
, lethargy, headache, high fever
Treatment would involve rest, fluids and the use of medication to relieve any symptoms.
For example paracetamol
can be used for any discomfort you are experiencing, a cough suppressant and mucolytic
can be used to help with cough.
These are available over the counter at your local pharmacy.
You can consider treating yourself, if the symptoms intensify then you can see your doctor.
It can take 7 to 10 days to recover from this viral illnesses and in some cases the cough can persist for 6 weeks.
I hope this helps
