Really? I used that for back pain and now off and on for muscle pain when I've overused a particular joint. I take it when needed and stop when it isn't needed.
Different people react differently. When I went through a severe flair up of my lower back – horrible jolting nerve pain along with extreme stiffness and spasms like I’d never had before (imagine the very worst Charlie Horse you’ve ever had, the type that jolts you awake at night, now imagine that across your entire lower back and down your legs every time you make even the slightest movement and it going on for days, getting little to no sleep), yes it was that bad.
The orthopedic gave me an Rx for Percocet (1 every 6 hours) and Cyclobenzaprine – Flexeril (1 every 4 hours). No, Cyclobenzaprine is not a Benzo but can be addictive for some and of course Percocet is one of those evil opioids. But thank god for them.
After about 4 days in my living room recliner in a bit of a stupor (as getting in and out of bed or up and down the stairs to get to my bedroom was out of the question) and icing for the 1st day followed by heat after that, I could finally get up and move around without screaming in pain. And I’m fairly pain tolerant. I’ve told people that I don’t know if the Percocet really took the pain completely away or just made me not care, but in any case, I was glad it was prescribed.
After the 4th day I stopped taking the Percocet completely and only took a Flexeril or a half of one at bedtime as needed I didn’t have any withdrawal symptoms from stopping the Percocet and had no urge to take them after most of the pain subsided. I had about 4 Percocet left and they sat in my medicine cabinet untouched until they expired and I disposed of them.
A friend of my OTOH, tore her ACL in a fall and had to have surgery. Her surgeon sent her home with an RX for Percocet, the same strength and dosage and I had gotten for my back. She took the Percocet also for 4 days but had a horrible time with withdrawal symptoms, anxiety, insomnia and severe constipation being the most noticeable.
I still use the Flexeril every once and a while when I feel the stiffness and soreness and the beginning of twinges of nerve pain coming on. But the best thing I found is doing stretching, lots and lots of stretching along with walking and core stability exercises.
