Hello . I Have Sustained A Repetitive Strain Injury From

Hello . I have sustained a repetitive strain injury from lifting at work. The injury is in my left wrist. And the MRI shows inflammation to the tendons. After three and a half months, one reumatologists is saying it's arthritis. Iam not sure it is. He recommends taking. Methotrexate , folic acid, and the steroid, Prednisolone. I agreed , but have yet to fill the prescription after reading about the side effects of both drugs. I want to get mr wrist better, but now Iam wondering if it's work the risk. If you have any input on this matter, I would appreciate your input. Thank you
