Arthritis is possible. You should also consider other podiatric conditions like plantar fasciitis, as well as arthritis.
Imaging the affected joints and the foot should be considered.
If there is associated finger pain, blood tests looking for systemic rheumatologic disorders should be done - such as rheumatoid arthritis or lupus. An ANA level and rheumatoid factor would be a good start.
Discussing the foot pain with a podiatrist and the joint pain with a rheumatologist can be considered.
These options can be discussed with your personal physician.
Followup with your personal physician is essential.
