what would cause a 29 year old male to have a rapid heartbeat and shaking while he is asleep and he doesnt realize it? He  has also had congestion in his nasal passages for many years; year around. He also started sweating profusely at times about a year ago.
Hello, I have gone through your query. Thanks for using Chat Doctor. I would like to know whether he has habit of snoring ? And also as you mentioned that he has nasal congestion it is possible that he has obstructive sleep apnea producing his symptoms. I suggest you to consult an ENT surgeon first and then if needed go for sleep study. My best wishes Chat Doctor.
