Filled tooth is really painfut

[Knka]

I got a silver filling in a tooth in the lower back of my mouth about a year and a half ago in Thailand. I didn't have any issues with it until recently. A few months ago I did notice a small cavity on the same tooth next to the filling. But the past few days the pain is bad, but for some reason if I hold my finger on top of the filling the pain disappears, also brushing seems to help for a short while.
The old hole under the filling was pretty big and deep (dark).

Do note I am petrified of the word root canal and I'd rather pull the tooth myself with working equipment

Sorry to say that the chances of it needing a root canal therapy are high. It appears that the caries have reached the pulp.Get an x-ray to get the final conclusion on it.

And as mentioned in your post, RCT or root canals are not at all a painful treatment. There are many a way to reduce the pain, or to avoid it.
