hello and welcome to HCM,
You seem to be having an upper respiratory tract
infection and you are in the right track to take symptomatic treatment till it becomes better.
You may take any pain killer like crocin
for the pain relief. Just make sure you take it after food and never in an empty stomach.
You may also add an anti reflux medication
if your throat feels sore
You may consider a throat swab if the symptoms persists or become severe and may be even consider antibiotic therapy in consultation with your doctor
take only warm fluids and do not strain when you speak
get well soon
Dr Sriram Nathan
