Thanks for writing in,
(AS) flare up can be controlled well with medications but cannot be avoided. You have to take proper medications for AS to avoid the progression of the disease. Seems you are only taking NSAID's for AS. Discuss with your doctor regarding starting you on DMARD's like Sulfasalazine
. Sometimes acute flare-ups need steroids
with/ without dose modification of DMARD's.
You have to take medications for AS regularly as advised for life long to control the disease progression. Physiotherapy
is very important to keep your back flexible.
Taking NSAID's for long term might cause gastritis
and renal impairment. Take them as per your doctor's advice.
Wish you a good health.
