I have a hard time with the heat too. Even a little swelling for me amplifies everything. I remembered you had been on the ACE inhibitor before and it absolutely may be coincidence that your symptoms increased after the dose change. How our CRPS reacts to meds we are on is just one of those things to consider with their use.

I had decent pain relief from nortriptyline but it makes me vasodilate like mad when it is warm which makes things worse. This probably doesn't bother most people. I ended up going down on it and doing about the same.

Don't cha just luv being special?
