Bleeding within the spinal cord that may cause sudden pain, weakness, or loss of sensation.
During the first six months, medical records that confirm a diagnosis of hematomyelia and show the condition is active support the 100% rating. After six months, the evidence that matters most is documentation of any residual symptoms and how severe they are. Records from treating providers describing ongoing problems — such as weakness, loss of sensation, or difficulty with movement — are relevant. Neurological examination findings that measure the degree of functional loss help establish severity. Statements from you or people who know you describing how residual symptoms affect your ability to work, get around, and manage daily tasks can show the real-world impact of those residuals. Because the post-six-month rating depends on which residuals remain and their severity, records that track changes in your condition over time are especially useful.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
