Thanks for asking - it is a good idea to share some additional things. He<br />has had an irregular heartbeat for several years - it was first treated<br />with an ablation in 2004. He received a pacemaker in 2014 and started to<br />take solatol along with a blood thinner. Gradually everything was adjusted<br />so that that arrhythmia was lessened and he no longer sensed the attacks.<br />In January of this year when we were checking if any meds may be causing<br />the night sweats, we talked with his cardiologist. She suggested stopping<br />the solatol - there was no change in the night sweats. Also, since there<br />was no stronger occurrence of the arrhythmia he never restarted that med.<br />He continues to take Eliquis. The only additional meds are Protonix (he<br />was diagnosed several years ago with potential Barrett's but later tests<br />were inconclusive and that has never caused any problems since) and<br />Aricept. He has always had low blood pressure and been sensitive to cold.<br /><br />Appreciate any other directions this may lead....<br />

I forgot to add a curious manifestation of the sweating -- they occur most profusely on the right side of his upper body - His arm, his chest and his upper back. There is a clear line of separation down the center line of his chest and back -- the left side of his body is warmer and not sweating.

@tavi The one-sided nature of the night sweats is interesting. I suppose your husband has seen a neurologist?

Yes - he saw a neurologist earlier this summer. There were no tests, just a meeting/conversation and the neurologist was unable to identify anything that might trigger the sweats.

@tavi That certainly is a mystery. I take it that no MRI or EEG was done. Here is a thought: Do you live in an area near a major medical center (one with a well-known medical school or one that does research)? Some medical mysteries can best be solved in an environment that uses a "team-approach" to problem solving. Just something to consider. It sounds like you could both use a good night's sleep. Once again best wishes you seek an answer. Teresa

We are in Portland - I will check to see if we might be able to identify folks at Oregon Health Sciences University who may provide a more comprehensive team approach. Thanks for your continued ideas!
