Hi Fabian, that was the case with my second gout attack. Pain started at base of the foot after a few long walks and took about 3 days to strike full blown (prior to starting allopurinol). After start allopurinol attacks would hit within hours during the day and last days or weeks and the last attack even lasted 2 months. What I have noticed however is as this last attack subsided the pain has moved from location to location on my foot. I guess it’s part of the whole UA clearance process.
The real question here is why are you still getting attacks after starting Uloric? Ideally you should be attack free if you’ve been on Uloric long enough to remove all accumulated deposits. How long have you been on Uloric and what are your current UA levels?
