Agree with K22, you must rest this and stop well before you get to the point of aggravating it again.
I was blessed with a great crew at work and learned very early on that some jobs could cause injury by repeating tasks you didn't think were that bad, but clearly were causing issues for folks. Hands, wrists, elbows, necks, and backs, were all very unforgiving.
You wouldn't think that just tightening screws could be dangerous, but some of the assembly techs were getting carpal tunnel damage from loading tasks or tightening screws. I spent a lot of time to make sure we all got educated on the medical and ergonomic issues, and I also spent time getting the tools or automation to eliminate or greatly reduce those motions.
I got lots of negative comments and criticism from some of the Ops Managers. I was part of R&D and beyond their reach and they viewed my habits as unnecessary. In their opinions I was coddling my crew and spending too much on automation. After 35 plus years, the facts were that my crews suffered a fraction of the injuries while out performing the others, not to mention the turnover rate was also very low in my labs.
Simple things like the right glasses, good lighting, adjustable microscopes, adjustable chairs and tables, powered drivers, etc. put your posture in the right place to protect your eyes, limbs, neck and spine. Get educated on the basics of what causes damage to your body and go from there.
Here is a book that my best man gave me later in life. I used to ignore it when it was in the airport book stores. He noticed I was still hurting after a being rear ended while skiing and the stuff in this book seemed basic or obvious, but it still helped.
I handed them out by the box-load to younger folks in the hope it would prevent the delusion that they were bulletproof.

In terms of reloading, at home I use as much automation as I can. Aside from some match shooting, I am prone to load very large batches for PD trips where it would be easy to get hurt. You would find several Dillon machines set up just for case prep steps like decapping, and I try and run the powdered trim/turn instead of the Wilson or Forester to avoid using my fingers. If you sit, make sure you are at the right height, get the right chair. Companies like InLine Fab make risers that can put the machines on the table anywhere from flush to elevated.
Yes these extra steps and things don't come free, they all cost money. But you will have to ask yourself what it costs you if you have to stop or if you hurt yourself. Get some rest and I hope you have a speedy recovery. (I hear Scotch works.... )
