Do I need to go back to the doctor

Currently suffering with a prolonged gout attack ( for me, previous 3 or 4 just lasted a day or two ). Started two weeks ago, my left foot exhibited all the classics, pain in the big toe and knuckle, red, swollen and as rigid as a plank of wood. Went to the doctors on day 4 as Naproxen wasn't working and was prescribed 4 days worth of Colchicine, this made very little difference although on day 4 there was an improvement. On day 5 I was prescribed 30mg/l one a day of Prednisolone which worked in that the swelling went, some movement returned and the redness reduced. The pain was still there though although not as bad as the early days.

So here I am on day 14 and my foot is no better than the day I finished the Prednisolone, in fact the swelling came back a little yesterday evening, back down tis morning. I am being super careful with my diet and drinking plenty. I'm now on nothing other than Naproxen.

Question.......is this a case of waiting it out and it will get better over time or do I need to go back to the doctor and is there something I should ask for or suggest ?
