How Long Will It Take?
How Much Will It Hurt?
- You might feel some numbness, weakness, or tingling for a few hours after the injection. Talk to your doctor about any activities that you may need to avoid.
- To reduce soreness, apply ice or a cold pack to the affected area for 15-20 minutes, a few times a day. Wrap the ice in a towel. Do not apply it directly to your skin.
- Take over-the-counter pain medicine as recommended by your doctor. The soreness should go away in a couple of days. Pain may return, though, when the anesthetic medicine wears off. It may take a few days before steroid medicine takes full effect.
- Follow your doctor’s instructions on cleaning the injection site.
- Check to see if you should avoid baths, pools, or whirlpools for 48 hours after the injection. Showers are generally safe right after this type of injection.
- Be sure to follow your doctor’s instructions.
