Chronic elbow pain concerns

I played table tennis for over 10 years, but I couldn't play for about three years due to COVID-19. Then, about a year ago, I started playing again, reminiscing about the old days, and I played hard. As a result, my muscles were weakened, and I ended up with tennis elbow. I went to the hospital, received physical therapy, and did arm strengthening exercises, which seemed to improve a little. However, my right arm started hurting, and perhaps because I used my left arm a lot, I developed tennis elbow in my left arm as well, and now my arm hurts again. It really feels like a chronic condition now. It even aches while I sleep, which has lowered my sleep quality and seriously affected my quality of life. I'm worried.
