I'm a 45 year old woman who recently started, every night in my sleep, groaning loudly. It wakes up my son in another room and is honestly, getting on his nerves...and rightfully so. In my research, I found "catathrenia", but that says its rare, but more common in men than women. This has been happening approximately two weeks and I don't know what to do to stop it. Is this worthy of visiting a doctor, and if so, what type of doctor? Is there anything I could try first?
