Well I don't know which body joint you have the OA in but in general...
OA means the cartilidge (or in the spine it's the disc shrinking) is disentagrateing or gone.
This causes the joint in question to become out of place a bit and need additional help from the surrounding nerves and muscles to hold it properly for functioning. So those overworked nerves and muscles can become swollen, stretched, stressed and quit sore at times.
Does that answer your question?
I take no prescription drugs for my OA.
If its in your knees it helps prevent some pain if you will put on athletic knee supports before beginning the task that causes the pain.
When OA in my knees is painful I put my legs up taking pressure off the knees.
If swollen I first use cold packs for 20 min. (The cold shrinks the muscle swelling)
Then after that heating pads for half an hour. (The warmth relaxes the muscles)
Sometimes Aspercream rubbed on at night helps.
I have been known to even sleep in the athletic knee supports where it was really bad. The supports do just that.. they help your sore muscles in supporting the out of wack joint. Giving those muscles that help lessens the resulting pain.
I use the same basic methods on my spinal OA in my back.
If all else fails a Tylenol Arthritis before bed lets me sleep.
I rarely take 2. They do make me drowsey.
A Thermacare back wrap has helped relax my bad back during the night in the past.
It helps tremendously to keep your skeleton lined up properly while sleeping.
It is very important, yet often overlooked.
I place a knee countour pillow between my legs juat a hair above my arthritic knees and a reg pillow between my legs at my ankles and calves.
AMAZEINGLY just this has done away with my morning lower back aches!
Took only 3 nights for the improvement to show up.
Try it 3 nights and you'll be addicted to the pillows!
Also Watch your posture, do not slump! Keep your shoulders back where they belong.
My spine began bending from the combination of OA and osteoporosis so those stretching muscles smashed the Bursa on my right hip and I suffered very bad reoccuring Bursisits for a couple years! THAT is painful.
Got steriod shot.. that helped get rid of the bursitis pain but only in one place.. I went to therapy got some relief.
A couple years of this on going bursitis caused by the muscles being streesed cuased by my OsteoArthritis & osteoporisis back problem gets old.
You get so tired of the constant pain.
So I found a Chiropractor.
A chiropractor may be able to help you with controlling pain from OA in the spine and neck (but not the hip or knees)
I LOVE what the Chiro has done for me in the past year!!!
I've been going fatithfully since last May.
My bursitis is gone,
I can bend and straighten
oh yeah my back feels 3 years younger now.
So whatever joint you have the OA in, keep your skeleton as lined up properly as possible and you'll have less pain.
That sounds easy.
BUT IS NOT Easy.
kEEPING THE SKELETON PROPERLY LINED UP IS HUGE TASK WHEN YOU HAVE OA.
But THAT IS THE KEY TO LESS PAIN.
