Spondylitis involves inflammation of the spine, which can cause chronic pain. Flat feet may contribute to poor alignment, increasing strain on the back. Since you don’t want medications, your next best bet is physiotherapy. However, if this gives you unnecessary pains, you will need to inform your doctor so he can give you more advice on the matter.
Consulting a specialist for personalized treatment plans can help manage symptoms effectively without relying on pain medications that cause side effects.
