After a spinal angiogram, the length of time it takes to recover can vary depending on the individual and any potential complications that may have occurred during the procedure. In general, patients may need to stay in the hospital for a few hours or overnight for observation before being discharged. They should avoid any strenuous activity for at least a day or two and refrain from any heavy lifting or rigorous exercise for several days to a week. The incision site may be sore or bruised for a few days, and patients may experience some numbness or tingling in the affected limb, but this typically resolves within a few days to a week. It's important to follow any specific instructions provided by the interventional neurologist or healthcare team to ensure a smooth and successful recovery.
