After spinal stenosis surgery you need to wait a week after the incision is completely removed before you can bathe. If there is redness in the incision area or at the sutures, the bathing period will also need to be extended. Most spinal stenosis surgeries involve a posterior approach to the incision, resulting in a long incision that requires regular cleaning and protection to keep the incision clean and dry to prevent infection from affecting healing. The stitches are usually removed 10 days after surgery, and bathing is not allowed until one week after the stitches are completely removed. The main reason why you can’t take a bath is because after the suture is removed, the tissue at the suture removal site is not completely healed, and it takes a week for the granulation tissue to finish growing, so if you take a bath too early, it may cause infection. Therefore, it is safest to bathe one week after the stitches are removed. In addition, if the surgical incision area is healed, but the skin at the incision or suture is still red, indicating that there is a local inflammatory reaction, at this time, it is also necessary to prolong the bathing time, to avoid bathing caused by infection.
