I have experienced 1-3 on your list...all since my RSD spread two years ago and got worse. The cognitive issues seem to be getting worse for me. I haven't been able to read a book in years (and I was a voracious reader before)...but I listen to audiobooks and those seem to be fine. When I try to actually read though I can only make it a page or two before I start re-reading sentences and paragraphs over and over without it sinking in. Now I've been having issues finding works. It took me two hours to come up with the word "dandelion" last week while walking around the yard. I knew it started with a D but could not come up with the word until hours later. This has been happening a LOT lately and is pretty scary.

The vertigo and fainting I have had too. Also dizziness and blurry vision. I was told that these were caused by the RSD and that it has to do with the fact that the sympathetic nervous system controls your blood pressure. Mine goes all wonky out of no where and causes these problems. I now have clonidine patches and that has pretty effectively controlled these symptoms. They used to happen multiple times a day and now I would say maybe a couple time a month...if that. Fainting...most doctors attributed that to the pain levels being so high for me...but it could be related to the same blood pressure issue I think because it usually happened in the middle of another episode of dizziness or vertigo.

Sleep problems I think we all have. Cognitive issues/sleep problems actually fall into one of the four categories they are supposed to use to diagnose RSD...I think. I went almost a year where the most sleep I got at night was 3 hours and it was almost never consecutive. Boy did I have the tv lineup down for those wee hours of the morning. Once I went on amitriptyline I was getting 3 consecutive hours of sleep a night...no more...but it was better than before. A couple months into tDCS treatments I began sleeping better and eventually got off the amitriptyline and now pretty regularly get 6-8 hours of consecutive sleep a night. I still have bad nights from time to time with flares...but those are much rarer now.
