Lumbar spine cerebrospinal fluid leak is mainly based on the site of the cerebrospinal fluid leak and symptoms to determine whether it has healed. Lumbar spine cerebrospinal fluid leakage is generally caused by the phenomenon of cerebrospinal fluid coming out from the surgical site after lumbar spine surgery, commonly known as cerebrospinal fluid leakage. Whether the site of cerebrospinal fluid leakage has healed or not can be seen firstly by checking whether there is any colorless and clear fluid oozing out of the surgical suture wound, if not, it is generally considered to have healed. On the other hand, you can also look at the symptoms, because if the cerebrospinal fluid continues to flow out, headache, dizziness, nausea, vomiting and other discomforts that may occur, if there is no such discomforts, consider that the cerebrospinal fluid leak has healed. Lumbar cerebrospinal fluid leakage should go to the regular hospital in time, and the doctor will give the correct judgment according to the specific condition whether the cerebrospinal fluid leakage has been healed or not.
