Lu - It seems you understood me to say that steroid injections worsened my condition....not sure why? I've only had cortisone injections twice, both times into my hip bursas for bursitis. The first 24-48 hours brought increased pain, but then improvement - which lasted 2-3 weeks. Which hardly seems worth the negative side effects of the steroid, although the relief, shortlived as it was, was very welcome.
My rheumy is now talking about the radiographic injections into the SI joints for the OA - he's referred me to a spine center in August, so we'll see what that doctor says. I've had some good results from massage therapy over the last 9 months, so I'm inclined to want to keep working on the strengthening and mechanical elements, and avoid the injections.
My therapist agrees it's a hard decision, but advises that the inflammation also does damage, so sometimes the steroid is needed to calm things down. She likes to say that prednisone/steroid use is like a credit card with a really high interest rate. A boon when you really need it - but it isn't without a downside that has to be dealt with. Since she can identify inflammation when she works on me, she is inclined to think it worth a try, because right now, I can't do the exercising and stretching without flaring things up - very frustrating.
I agree with Kasbern. I over did the heat packs for awhile. I still use heat most often - but also use cold and /or alternate, as sometimes that feels better. I believe it does have to do with muscle spasm vs. inflammation......and sometimes there is both going on!
For cold and heat, I really like www.fomentek.com - they sell plastic, fillable "bags". They seal beautifully, last forever, and you can use either cold or warm water and they just sort of mold around you. I also use microwavable rice bags for heat, but sometimes it's hard to get just the right temperature.
