I have had a number of epidural steroid injections in my lumbar spine.No the shot won't stop the
percocets to stop working.It should help lessen your pain so that you won't need the percocets.
Yes, your neck can be sore for a few days so don't worry about that unless it gets worse or doesn't get better within a week.
The other thing I wanted to mention is the
oxycodone and
tylenol (percocet) is a fast acting narcotic pain killer and is generally used for acute pain last usually no mre than a few weeks.After that, daily use of percocets increases the risk of tolerance.Once you start to get toerant to the drug then it loses it's effectiveness very quickly.
This were switching to a sustained release opiate like
oxycontin (oxycodone in a sustained release pill).
Oxycontin is very successful for chronic pain and the percocet is then used occasionally for break thru pain.Good luck and give that injection a week or so to kick in........Dave
