tennis elbow pain/symptoms -other names for it golfers elbow, cubital tunnel , epicondylitis.

Sometimes the pain/symptoms can be caused by irritations or compression on the nerve up near the neck/shoulder/collarbone.
The wood carving is what made me think it might be based higher up, the posture , pushing, holding the wood, detailed work...

I had elbow pain (assembly /production work) and it was based from the tension & spasms in my neck & upperback muscles, treating the elbow itself didn't help much, then when posture & upper muscles were treated the elbow pain faded away.

This could be caused by forward head/shoulders posture, or trigger points in the muscles of the upper back or neck muscles.

Here is a neat trigger point chart that is clickable - you can find elbow pain then click it and the images will show you where to feel for possible trigger points, then how to treat it.

If you ask a friend or look in a mirror from the side you can check your head/shoulder alignment.
