Welcome to HealingWell and the Heart & Cardiovascular Forum. I am glad to read the tests done in the ER were all OK.
If you experience especially bothersome symptoms — such as significant airway obstruction, chronic sinusitis or frequent nosebleeds — you may consider surgery to correct a deviated septum. Are you working with a ENT physician re your treatment of your deviated septum ?
Also when we have major medical problems that are bothering us it is easy to find yourself becoming anxious. We have a great forum for anxiety so please do post in that forum and you will find many wonderful and caring people who will support you and help you learn methods to reduce your anxiety.
I hope this info helps you in some small way !
