Hi Cindy, go to any search engines like alta vista,etc. type in the subject RSDS and you will find lots of sites about RSD, explaining what you need to know. If you are on medication that could be the cause of the throat closing up, ck with your doctor if you are. I do a lot of research on the internet for RSDS and I was amazed on how many sites there are, one good one is www.rsdhope.org/ I hope this helped you if you would like more info let me know and I will try to help you. I also have rsd throughout my body so I know the pain, etc you are going through and rsd is now becoming more known. take care
