Yes, but it is not dangerous. Usually transient. Goes away without a sequel.
No
Local anesthetics are generally very safe and serious problems are rare. You may have:

-some discomfort when the injection is given
-a tingling sensation as the medication wears off
-possibly some minor bruising, bleeding or soreness where the injection was given

You shouldn't experience any significant side effects. You should move carefully until the anesthetic has worn off as you may not notice if you injure yourself. Some people experience temporary side effects from a local anesthetic, such as:

-dizziness
-headaches
-blurred vision
-twitching muscles
-continuing numbness, weakness, or pins and needles

These problems will usually pass, but you should tell the healthcare professional in charge of your care if you experience any.
I’m not an expert on local anesthetics and peripheral nerve blocks. I’m assuming that’s what you had. Numbness can last to some degree for days after a nerve block. Muscle twitching may just be the nerves coming back at various rates and should subside. But I would definitely contact the surgeon and anesthesiologist if this persists.
