Treatment Options: Unless there is a reason you can not take them, standard over the counter analgesics include anti-inflammatory medications such as Ibuprofen or naproxen. They work best if taken on a regular schedule for the length of the short tem pain (a couple of days) versus sporadically.Tylenol (acetaminophen) can also be taken during this time as well. Otherwise this should be evaluated by an appropriately trained provider.
