Great question 😀 Speaking with your doctor about your pain doesn't have to be difficult. Depending on which doctor you are most comfortable with and possible comorbidities you may be experiencing, you could start the conversation with a few different doctors. Many people start with their primary care doctor, but as you are scheduled for a hip replacement, I'd imagine that you possibly have an orthopedist or even a rheumatologist.
If you have a rheumatologist, they are your best bet. You could start by explaining the pain you have been experiencing (severity, locations, and how often) and be sure to bring any documentation you might have ( for example-pics of swollen fingers). They are likely to send you for blood work and testing. Here is a great link to information it would be good to know about diagnosis. https://rheumatoidarthritis.net/diagnosis/
The most important thing is to be clear, prepared, and choose a doctor that you are most comfortable with. Finding the right diagnosis of RA can be a long process so be prepared to be patient and if needed,get a second or third opinion. I'm sure the rest of our community will chime in with tips on how to talk with your doctor as well. You can also use the search bar at the top to find more articles on the topic.
