Hello. Since details like age, risk factors, other joint involvement are not mentioned, I will list the possibilities. 1. Pain which gets worse on getting up in the morning generally suggests an inflammatory arthritis most common is which rheumatoid arthritis. If you are in your 40s or 50s, and have pain in multiple joints like the joints of the hands and feet or back pain which gets better as the day progresses, it is more likely that you have rheumatoid arthritis. I would advise an Xray of the affected foot, blood test called RA factor and anti-CCP antibody. If these are positive, you need a consultation with your rheumatologist. 2. Another common condition is gout. Attacks typically start suddenly and the affected joint becomes red, inflammed and painful. A blood test for serum uric acid confirms this. 3. If you have a history of injury to the foot, then it is likely that your pain is musculoskeletal. It may be a sprain or even a hairline fracture. For now, I would advise: 1. Hot water fomentation to the joint. 2. Rest or immobilisation by a crepe bandage or splint. 3. Pain killers like paracetamol, ibuprofen and anti-inflammatory drugs like serratiopeptidase. These are available over the counter in most countries. Avoid use for more than 10 days, and if you are a diabetic. Tramadol is safer for diabetics. 4. Observe for 2 days. If pain does not get better, it needs more evaluation like an Xray and the blood tests which mentioned earlier. Hope this helps. Wishing you a speedy recovery. Regards, Dr Geeta
