First, let me say,
I am not a doctor.
However, I do know from personal experience and research that cortisone injections can be very painful at the time of the injection due to a side effect called a
cortisone flare. The fact that the doctor used a different anti-inflammatory may be why this particular injection was less painful than previous injections. Please note that a cortisone flare does not mean that the cortisone isn't working. Cortisone usually takes 48-72 hours in order to reduce swelling and inflammation, which is coincidentally (or not) how long the pain from the cortisone flare lasts.
Thanks for the explanation. The other injections that my wife has received were painful, but had no effects at when the first pain had gone away. She also needs stronger doses of other pain killers to feel any effect, and some, such as morphine, cause violent reactions. Many years ago, at her first first back operation, she was supposed to wake up after an hour, but was unconscious for six hours. When she woke up she complained about pains, and the nurse gave her a morphine injection which caused my wife to throw up and pass out for another couple of hours. The anaesthetics that dentists use, also have little effect apart from a strong pain, so my wife usually has her dental work done without anaesthetics.
Chiropractic manipulation is very unlikely to help. The premise of chiropractic care is that there are dislocations or imbalances in the spine, called subluxations, that cause a variety of ills throughout the body. Chiropractic "adjustments" supposedly move the dislocated or imbalanced vertebrae in the spine back into alignment, banishing the subluxations, and thereby banishing the patient's ills.
Well, this doctor never mentioned the word 'chiropractic', that was my interpretation of the manipulation that I recognised. The theory may be bollocks, but if it works, it works, and in this case there was a significant improvement of the mobility of the legs.
It has been my impression that the problems with the manipulations is not that they do not work, but that some are dangerous, and other therapies exist without the dangers.
I have myself had a "miraculous" healing some years ago, when doctors variously pronounced that I had a 'small blood clot' in the leg, or that the pain that had made me hopple around for more than a month was 'just one of those things that happen with age', and that I should get used to it. As I have described previously on these pages, I went to a chiro, and she immediately noted a significant swelling of my foot that I had not noticed myself, because it was painless. She asked me to stand on my toes, and on my "bad" leg, i was hardly able to do it. After making a flick with my foot, and popping my toes, she again asked me to stand on my toes, and this time I could do it almost equally well on both feet. I did not hobble after that, and the swelling disappeared after a few days.
A couple of months earlier, I had had a bicycle accident and my pains were probably caused by this, even though they had started some time after.
The chiro never spoke about subluxations, or adjusting anything, and do not see why the application of a manipulation would be woo in itself. I have spoken to ordinary physiotherapists who said that they also applied some of the same manipulations that chinos do, just like this Austrian doctor. My own theory is that the manipulations cause a light numbing of pains in the affected area, just like an anaesthetic, and that this sometimes can break the vicious circle that keeps inflammations going. The real problem is that neck manipulations can kill you, and who knows what side effects the other manipulations can have?
Please be very careful from this point on. This man hasn't done anything harmful to your wife or tried to sell you any outrageously expensive useless items so far, but there's still time. The real money in chiropractic and homeopathy is in "supplements" --- overpriced vitamins and homeopathic cures that make your spine feel better by reducing the strain on your lower back through reducing the weight of the wallet in your back pocket.
There is no danger here. We are back in Denmark

However, visiting a specialist doctor in Austria as a private patient
is expensive, so you can consider us fleeced nevertheless!
This night was the first time for a long time where my wife has not been woken up by pains, so there is hope! The injection was five days ago, so if it was the cause, it has taken some days to work (but the increased mobility was apparent already yesterday).
