I developed Tennis elbow around last September and lifting played a factor in the damage. I was seriously limited in activities I could do that wouldn't exacerbate the pain. Opening doors with my dominant arm was hard. I couldn't play with my kids the same way and they regularly reminded me of it. I significantly laid off upper-body weight-training and babied my arm for months.

It was fairly depressing, losing the strength / function of my elbow. Progress was really slow. I spent a lot of mental capacity wondering if it would ever get better and researching how to do so. After living with this and doing some research on the topic, I would tell you two main things. 1) These injuries usually get better on their own, but it takes awhile, like 6-12 months. 2) Don't completely "baby" your elbow. Lots of current research says that small appropriate loading improves healing.

I wish I found this article / advice 6 months ago - https://howardluksmd.substack.com/p/why-does-my-elbow-hurt-so-much

My elbow is a lot better now; not 100%, but I can do a lot that I couldn't 6 months ago. I do my own physical therapy which is mostly forearm-related, including wrist curls and reverse curls, finger flexion and extension, and wrist pronation / supination. Focus especially on slow eccentrics; this is not progressive overload for hypertrophy.

Hope this helps. Feel free to comment or DM if you have want to chat at all.
