I'm 33, Female, 5'-3", and +/- 145 lbs, I have been (type 1) diabetic for the last 30 years and have had back surgery for tethered cord (spina bifida occulta) when I was 16... (just as an FYI) This is a looooong ramble, so be prepared (last paragraph may be all you need to read):
I have been doing karate for the past 5.5 years or so, and about 1 year into it, I hurt my hip doing a kick badly. It hurt pretty bad for a long time, but progressivly got better (though never the same) and has since been getting progressively worse.
The pain is not much in the way of being "debilitating" in any way (on a scale of 1-10... usually only 1-3 in day to day normal activities, up to 5 when trying to sleep, and up to 8 (but not always) when doing vigorous activity... like Karate.). The general feeling is a lound clunking sensation at the front of the hip when I bend my knee and then push my leg down (and also a feeling of "catching" when I just bend my knee in a weight bearing, static position. I also have to repeatedly "reset" the ligament to the right place while lying on my back in bed (as well as a few dozen times in a Karate class).
I had been investigating online, ways to help my situation when I stumbled upon "Prolotherapy" and I thought to myself "this is the answer!!" (I am mildly hypermobile anyway... have had a total of 6 shoulder dislocations and some mild knee issues) So I got all excited and went to see a Prolotherapy Doctor (I had to travel/take a flight to do so, as there are none anywhere around where I live) and after he examined me... he almost had a puzzled look about him... and I asked him what was up? He seemed almost as though I wasnt presenting with any kind of definitive enough pain, and he said he has the feeling that it was an issue with the Sacroiliac... but I got the feeling from him that it wasnt presenting itself "normally" as I had/have no actual pain in my back, just in my hip and no revalation of pain at all through palpation. I was personally convinced that if Prolotherapy was to work... it would have to be done on my hip joint, to the front as thats where it "feels" lax due to the clunking sensation that I always get and also where the pain is. (after further investigation online I've found that clunking to probably be due to tightness and not laxity of that particular ligament and so maybe the SI joint is indeed the right place to target for its laxity).
His first recommendation was to get an MRI (which shows absolutely nothing wrong accept some very mild inflamation) so that ruled out for him any posibility of labrum tears amongst other things, but as MRIs arnt all that good at revealing SI problems he still wants to do a diagnostic injection instead of just going ahead with the prolotherapy to the SI joint because he's still not sure if that's where he should target as my case doesnt present itself in the most usual way.
Anyway... I wrote that big long rambel to give you some background to ask this question: If there is laxity in my SI joint (which I suppose prolotherapy may help with) will the diagnostic be effective if given to my SI joint, if there is not really any pain in that area (and therefore I can only guess no inflamation either) only at the front of the hip. I still believe the prolotherapy itself may work for the laxity of the SI joint to put everything else where it should be and stop the pain in the hip, I guess I just dont think that the diagnostic itself will work as there isnt much inflamation where the diagnostic steroid would be going? (also he's concerned with giving a diabetic a steroid... I'm not too bothered by it though, as I think I could figure out the higher insulin dosages needed)
Any input appreciated.
