Hello and welcome to HCM.
Thanks for posting your query here.
The symptoms you are saying about correlates with pharyngitis
. But you had the antibiotic within a short time. Good. This reduces the chance of spreading of the infection. Please continue the antibiotic for 5 days. For cold
you can take some antihistaminics. Dolo 650
can reduce your headache. The tiredness
is because of the antibiotics.
Please take multivitamins to reduce the tiredness.
Take lots of fluids and do some steam inhalation which will ease you.
If the symptoms wont subside within 2 days get an ENT check along with blood check.
Hope this is helpful to you.
