Hey there chiynita, and pleased to "meet" you.
There is a kind of doctor that specializes in conditions like arthritis, it's called a "rheumatologist". My ex-wife had a horrible case of arthritis all over her body. Her docs gave her a variety of meds just for arthritis called "anti-inflamatories". Aspirin is a very, very mild kind of anti-inflamatory, steroid shots are middle of the road and the heavy duty ones are also used for cancer patients (like Methotrexate). These meds reduce the inflamation, which in turn reduces the pain a _lot_.
See if you can find a rheumatologist, they were wonderful for my ex-wife.
