In need of a Drs note for nerve damage...best way to go about this?

33F. nerve damage in hands. my work won't give me accomodations (electric scissors) unless I have a Drs note. my hands hurt every day especially in the mornings and I have to brush my teeth a specific way because I usually can't bend my fingers without it hurting in the morning. I'm only 33. my job is 80% cutting very hard to cut material. the problem is I don't have insurance and am not trying to go drop $300 dollars just to have a Dr write a note for me. what is the quickest/cheapest way to go about this? can I get a doctors note from a pharmacy, like a walgreens? is there another way to go about this that I'm not aware of? I'm sorry if this isn't the right place for this. if not, I'm more than happy to have a better sub recommended. thanks in advance for any help, I appreciate y'all for reading.
