Injection trauma: The needles we use are extremely sharp and fine, but as they penetrate the tissue they may injure muscles, blood vessels or other tissues. This almost always quickly subsides (1-3 days) although I cannot give you a definite time frame. You can use warm salt water rinses and OTC pain medication such as Advil, Motrin, Aleve (naproxen) or what you would normally take for a headache.
