Back fasciitis usually lasts 1-2 weeks and can be clinically divided into acute and chronic fasciitis. Acute fasciitis usually lasts about 3-7 days, and some may last up to 2 weeks, after which if not cured, it can develop into chronic fasciitis, which can recur. With back fasciitis, you should avoid excessive bending or activity during the acute period, avoid standing and sitting for long periods of time, properly stretch the muscles and ligaments of the lower back, and apply local heat, and take oral anti-inflammatory and analgesic medications or muscle relaxants. Back fasciitis can be completely prevented by paying attention to sitting posture, avoiding prolonged bending or prolonged standing and sitting, and by developing good habits of self-exercise, and by doing proper functional exercises of the low back muscles to prevent it.
