I have CRPS as well after a fracture.
It is incredibly hard to fix according to my consultant, but keep going and hopefully things will improve.
I had initially truly agonising pain, and it was easily hitting the most I could bear, burning (as in on fire) feeling, v. painful shooting pains, severe swelling and odd thickness of nail. Feelings of revulsion towards that area. Hyper sensitivity. I nearly passed out having a scan, and even the smallest breeze is agony. It has been really hard to deal with and I have had my fair share of major operations and two children without pain relief.
After lots of physio and 8 weeks later I now have:
less swelling, hypersensitivity is easing, burning pain has gone but still finding it hard to move the limb.
I have been using fabrics, fur, everything to desensitise the area this has helped the extreme end of the condition. I have 'love bombed' and told myself over and over how much that part of me is loved and part of me. Sounds strange but seems to be working a little. I am stroking, massaging and moving it constantly. I am trying to use it normally (it still feels completely broken but it isn't)
I have a referral to the bath clinic and go on the 21st. Not sure what to expect....
Gaba was horrendous. I could not tolerate it, I was supposed to take 9 a day, and even 2 made me feel so spaced out, like a zombie, I felt sick and could not focus in a tiny bit. I can't recommend it at all.
I have since been given amitriptyline but have had a stomach bug so I am yet to try it. I am dreading taking it when I am better.
I am so sorry your child has this, it is so awful. I have had so many huge health problems and this has been the worst by far.
Sending you both
and prayers for a quick recovery.
