Nerve Block frequently asked questions
Occipital Nerve Block
What is an occipital nerve block?
An occipital nerve block is an injection of a steroid or other medication around the greater and lesser occipital nerves that are located on the back of the head just above the neck area.
What is the purpose of an occipital nerve block?
The steroid injected reduces the inflammation and swelling of tissue around the occipital nerves. This may in turn reduce pain, and other symptoms caused by inflammation or irritation of the nerves and surrounding structures. Typically, headaches over the back of the head, including certain types of tension headaches and migraine headaches, may respond to occipital nerve blocks.
What is actually injected?
The injection consists of a local anesthetic and a steroid medication.
Will the occipital nerve block hurt?
The procedure involves inserting a needle through skin and deeper tissues. So, there is some pain involved. However, the skin and deeper tissues are numbed with a local anesthetic using a very thin needle during the performance of the block.
How is the occipital nerve block performed?
It is done with the patient seated or lying down. The skin and hair of the back of the head are cleaned with antiseptic solution and then the injection is carried out.
What should I expect after the occipital nerve block?
Immediately after the injection, you may feel that your pain may be gone or quite less. This is due to the local anesthetic injected. This will last only for a few hours. Your pain may return and you may have a sore head for a day or two. This is due to the mechanical process of needle insertion as well as initial irritation from the steroid itself. You should start noticing a more lasting pain relief starting the third day or so.
What should I do after the occipital nerve block?
You will rest for a while in the office. Most patients can drive themselves home. We advise the patient to take it easy for several hours after the procedure. You may want to apply ice to the injected area. You can perform any activity you can tolerate.
Can I go to work to work the next day?
Unless there are complications, you should be able to return to work the next day. The most common thing you may feel is a sore head at the injection site.
How long does the effect of the medication last?
The immediate effect is usually from the local anesthetic injected. This wears off in a few hours. The steroid starts working in about 3 to 5 days and its effect can last for several days to a few months.
What are the risks and side effects of occipital nerve blocks?
Generally speaking, this procedure is safe. However, with any procedure there are risks, side effects and possibility of complications. The most common side effect is temporary pain at the injection site. Other uncommon risks involve infection, bleeding, worsening of symptoms etc. Fortunately, serious side effects and complications are uncommon.
