9mm stone + some more waiting

I went to the hospital 2 months ago with a 9mm stone and they blasted it and put a stent in. I have a physical job and outdoors in Phoenix. I’ve managed to keep the pain down with Tylenol (I can’t do my job on pain killers). I have a second surgery set for mid May to have stent and more stones removed and another stent put in. Today was the first day I’ve called out of work because of it and I’m not sure what’s different now. I’ve been in constant pain since it’s been put in but it’s been manageable for the most part. What helped yous? It’s been in for a few months now and I’m getting worried about infection.
