Fasciitis may cause back pain after taking a deep breath, but not in all people. Fascia is a membrane that wraps around the surface of the muscles and serves to reduce friction between tissues, regulate and restrain tendons, and act as a cushioning cushion. When the fascia is subjected to acute and chronic injuries, such as exceeding the capacity of the fascia, the fascia will tear, hemorrhage, edema and other inflammatory reactions, thus causing local muscle pain, stiffness and other symptoms. If there is fasciitis in the back, it will cause localized pulling when breathing deeply, thus causing back pain. Fasciitis patients, in general, should develop good habits, pay attention to local warmth. Can use non-steroidal anti-inflammatory analgesic drugs such as diclofenac sodium and other treatment. Can also be combined with hot compresses, massage, baking electricity and other methods of treatment, for the improvement of symptoms can play a role. If the symptoms of fasciitis are more serious, or the condition is recurring, you should go to the hospital in time for further diagnosis and treatment.
