Gout is something which ought to be managed with a longer time horizon but until you get serious about that…
Colchicine and indomethacin do not address the cause of gout but are effective to manage the symptoms if taken in sufficently large doses.
Watch for side effects getting worse over time. Should that happen to you, you’ll be better off in the long run if you don’t ignore it.
Outside of drugs, hydratation and blood flow matter. Also, best avoid cold. You ought to drink lots of water (within reason) and relax as much as possible. Support your foot to relieve your muscles if needed but make sure to keep moving your foot regularly. If at all possible, occasionally get your heart pumping with whatever exercise doesn’t hurt your foot or perhaps with hot showers. Some people bathe their foot in hot water which addresses several of the aforementioned concerns.
Last but not least, people who have untreated gout, aren’t monitoring their liver and kidneys and take drugs such as indomethacin should be very careful with alcohol.
