A doctor will need to examine, determine your uric acid level (laboratory work-up) and other blood tests. X-ray might be needed to rule out arthritis
and other joint diseases.
are the drug of choice for gouty crisis.
will have to be checked and properly controlled.
You will need to reduce quantity of red meat (if you do consume) and any other source of food that can increase level of uric acid in your system.
injection can also work for gouty crisis and if you had other forms of arthritis that will work perfectly.
Hope this helps
