A hot towel will not clear up a cold sore.
A cold sore is caused by the herpes simplex virus and will generally clear up in time. I did have one student in my classroom who kept picking at a cold sore and now has a scar in that area.
it depends how severe the cold sore is, personally the best remedy for me is mixing baking soda and a little bit of water to make a paste and applying it the sore it might burn but it will clear within 5 days and look better in 3.
before penicillin ............ many people died of infections such as sore throat and diseases
You can get a cold sore wet.
That is not a very good drug for sore throat. You need to take penicillin or azithromycin.
It might if the sore throat is due to an infection by bacteria that are sensitive to penicillin, and most bacteria that cause sore throats are. However, the most common causes of a sore throat are viruses and viral infections are not treated with antibiotics like penicillin, since viruses (e.g., the cold and flu viruses) are not sensitive to or "killed" by antibiotics like bacteria are.
