sore on chin and excessive drooling

Good day everyone,

I was hoping if someone could help me,

My cat has this sore on her chin that has been there for months. I tried applying antibacterial cream but she uses her paw to lick it off. I attached a photo of the sore.
A week ago she started drooling excessively and i am so worried because last time she was drooling excessively she had a quivering chin , she was poisoned. I had to take her to a vet in another town because the area i live in closed their vet. Im just worried because I do not know what the sudden excessive drooling means and if it is connected to the sore on the chin in some way.
Has anyone else encountered these problems if so what can i do to help her?
Thank you

These two issues may be unrelated, however, I think a vet visit is in order to get to the bottom of both.  Drooling can be a symptom of an oral health problem *or* something more serious.  And a sore that doesn't heal definitely needs checked out.  It could be something routine, no need to panic, but you need to know that it isn't the result of a compromised immune system or a disease like diabetes.  

Best wishes and keep us updated!

I agree with the vet visit idea! The drooling could be caused by many things and only a vet will be able to determine the cause. I would go as soon as possible.

The chin sore could be acne. Plastic dishes are probably the most common cause of feline (or canine) acne. The best dishes to use are stainless steel or some type of glazed ceramic or china, and they need to be cleaned at least once a day, if not after every meal.

It is a good idea to periodically clean plastic toys, as well. My dog got awful acne from the bacteria on her frisbees. I couldn't possibly stop throwing them for her, so I washed them with hot, soapy water and wiped her chin several times a day with a warm, wet paper towel. That helped a lot.
