welcome to HCM!
you seem to be having is Acid reflux
it occurs when the lower esophageal sphincter fails to close properly. As a result, acidic stomach contents spill into the esophagus, irritating and damaging its tissue.
A sore throat
caused by acid reflux usually occurs in the morning when you wake up. You can take over-the-counter antacid and see if it helps.
Another possibility is upper respiratory tract
infection as there is sharp pain
in your throat .weakness,body ache.in that case you will need antibiotics and anti inflammatory analgesics .
hope this will help you!
