Hello, You are right in that it is an inflammation and more likely to be an arthritis involving the small joints of the feet. It is likely to be rheumatoid or sero-negative arthritis. You could a rheumatoid factor and take a X-ray of the feet. These would help in the diagnosis. If the pain is significant, you could use an anti-inflammatory medicine like celecoxib for relief till the diagnosis is evident. Best wishes,
