sore throat, extreme stabbing pain.

On one side of back of throat. for an hour after wakening and when drowsy. Penicillin since 1st. Oct

Hi, Malcolm!
This sharp pain especially upon waking up is quite characteristic of a throat infection. However, I advise you not to self-medicate.
If the penicillin was prescribed by your doctor, that’s fine, just make sure you follow the treatment to the end.
I hope you are already feeling better.
