Hi Thanks for choosing HCM for your query. Indocap is one of the most potent NSAID found to be useful in the treatment of inflammatory joint conditions including ankylosing spondylitis. It is known to cause the following side effects: Acidity related stomach pain, diarrhea, bloating sensation, headache, dizziness. etc. It is used to relieve inflammation, pain and stiffness. There is no cure for ankylosing spondylitis, but treatments can decrease & lessen your your symptoms. A common treatment regimen involves medication, exercise and possibly physiotherapy, good posture practices, and other treatment options such as applying heat/cold to help relax muscles and reduce joint pain. In severe cases of AS, surgery may also be an option. The duration of your condition may change over time, and you may experience relapses and remissions throughout your life. But most people are able to live a normal healthy life despite a diagnosis of ankylosing spondylitis. Hope your query is being explained. Kindly rate the answer if you are convinced.
