This is what I do when I am in a flare. I hope this helps and the worst of your pain eases. It is never is one thing that works, it is a combination of doing many things and trying everything I think might help.
Alternate heat and ice. Don't leave ice directly on your skin for more than a few minutes to avoid damage.
TENS unit for back pain Try it on other areas where you have pain.
Linament. Strong as you can find. I like one with Methyl Salicylate in it as it helps with pain.
Anti inflammatory gels such as Voltaren or Nurofen.
A sauna helps you sweat out the toxins in your body.
Hebal infusions. Cats Claw Powder (from a plant not a cat) has Diuretic and anti inflammatory properties. Pau d'Arco has anti inflammatory propeties. Reishi Mushroom is a tonic sedative which might help you sleep.
Valerian may also help you sleep better and is readily available in capsule form.
Epsom salt baths can help joint pain and swelling. I buy a large supply form a Rural suppier, much cheaper.
Massage - not too hard. Could be a few days afterwards before you feel the benefit and the hurt from the massage goes away. But well worth it.
Eelectric Blanket to warm my body.
Padding on the bed, a wool underlay and the egg carton foam. A long body pillow and more pillows and cushions.
Predisone for a couple weeks and don't over do it as there are long term bad side affects.
Relaxation therapy and meditation
Plenty of rest
Lavender on your pillow is suppose to help you sleep. It smells good and is calming.
Remove the stress from you life. We sometimes don't realise how a little stress can impact on us.
Be extra diligent with your diet. No refined sugars at all. No caffiene for a while.
Supplements after a consultation with someone in a field that knows what they are doing.
Do something that distracts you from your pain. Even if it is only watching a DVD.
