This is a rare complication that may occur if a small hole is made in the fibrous sac and does not close up after the needle puncture. These small holes are only made in less than 1% of epidural injections and usually heal on their own. The spinal fluid inside can leak out, and when severe, the brain loses the cushioning effect of the fluid, which causes a severe headache when you sit or stand. These types of headaches occur typically about 2-3 days after the procedure and are positional - they come on when you sit or stand and go away when you lie down. If you do develop a spinal headache, it is OK to treat yourself. As long as you do not feel ill and have no fever and the headache goes away when you lay down, you may treat yourself with 24 hours of bed rest with bathroom privileges while drinking plenty of fluids. This almost always works. If it does not, contact the radiologist who performed the procedure or your referring physician. A procedure (called an epidural blood patch) can be performed in the hospital that has a very high success rate in treating spinal headaches.
For many people, back pain goes away on its own or with nonsurgical treatments. Epidural steroid injections shouldn't typically be used as a first-line therapy for back pain relief, but that doesn't mean they can't play a role in treating pain. But injections won't cure the underlying cause of back pain, and they provide only temporary relief. Unfortunately, in many cases, chronic back pain can't be cured, but must instead be managed, like other chronic conditionsand patients must have realistic expectations of what epidurals can do.
Professor Adolfo Bronstein, lead author on the paper from the Department of Medicine at Imperial, said: "Meniere's disease causes disabling attacks of dizziness that in some cases can leave people unable to work. However at the moment the only treatment we have for severe cases is a so-called 'destructive treatment' that kill cells in the inner ear. Doctors, including ourselves, always assumed steroid injections were less effective than the current treatment, but we were surprised to see they work just as well as gentamicin, but do much less harm."
