I wonder if the "swelling" / "lump of swelling" is that "marbly feeling" I know I get when my SI is inflamed and I get "fluid" in my joints. Its not a lot like "sausage digits" that some people get. But its enough that the PTs, chiros, physiatrists, and interventionalists can feel it. And have taught me what it feels like as well.
Maybe its not something that everyone gets? but for me, I can relate to it.
May I suggest Ice packs?
Even with the flector patches, ultrasound, nsaids, and even if I take a course of steroids (dose pack) or get a steroid injection, I still use a lot, and i mean a lot, of ice.
or alternating the ice and heat. sit on ice. take hot showers. but mostly ice.
for me, ice is:
1. a great pain reliever
2. a great anti-inflammatory
3. a great muscle relaxant
heat is good for relaxing muscles as well
as is a good muscle relaxant (i take zanaflex). normally every night. but when in a flare, i'll take it every 6 hours if i need to. it helps, but really, for me, ice helps the very most.
ultrasound through a PT can also help.
i tend to approach it from all the angles i can. all the things you are doing. plus the other things i mentioned.
it used to take 1-3 months to recover in the past from a bad flare.
Now it takes more like a week.
Also as Tim stated, every day I avoid the following as my SI has gotten that sensitive, but by avoiding the following, its often nearly pain free now:
things i avoid:
stairs, i always take the elevator
hills, i just try to avoid walking up or down them, thankfully i don't live in SF
sweeping, mopping, vacuuming, shoveling, raking (swiveling the pelvis)
sadly swimming is out as well (though if i didn't do breast stroke kick maybe i could swim?)
bending at a 45-90 degree angle at the hips for more than a few seconds
lifting or more importantly bending over slightly and setting down chairs
lifting anything too heavy
i know that sounds like a lot to avoid, but you just get into habits and its not that hard.
lucky my husband will do the house chores i can't do. not everyone has that luxury.
so, if i were you, i'd use some ice. maybe see a PT for ultrasound (manual PT, not someone who thinks you just need to exercise, as john says, you don't exercise something when its in an acute flare). and if there is an nsaid you can take for just a few days, i know Aleve will help me for a few days when i use it rarely, though others do argue that it contributes to leaky gut, but for me, sometimes i feel i have no choice. i'll do the steroids first, but if its been too recent since the last course of steroids, i'll use aleve for a few days. and still, always lots of ice.
did i mention the ice
