Hello! I'm going through the same thing! In August I tried to not draw at all to try and heal but it did nothing. I went to the doctor and they were no help. I've been stretching adjusting my seat, trying to sit in different positions. I found that traditional drawing doesn't hurt as much.
I kept telling people about it, but not to many people realize how upsetting and even depressing it can get when you're an artist and physically can't make any art. Even some artists themselves! I've stopped digital completely and just focused on traditional because I can't just stop art completely for the time being.
If you ever want to talk about it message me! I hope you feel better and can start making ASAP! These look very nice.
