In my case, I underwent a full sleep study and it confirmed I have mild obstructive sleep apnea (troubling too even when awake if I am sitting and leaning back).
I weight problem was described by the Pulmonary doctor (sleep study related) that my OSA was due at lest in part to my being obese... that said, I considered myself over weight, 250 at 6' 5" + but I said I'd rather try to lose weight than go to a CPAP. I have lost 25 pounds (10%) and fluctuate from that upward 5 or 6 pounds depending on how successful I am at avoiding sweets... love 'em : ( In any case, the OAS symptoms stopped when I had lost only 10 pounds or so. This needs to be confirmed, and I will address that with an at-home recording oximeter run supervised by my Primary Care doctor - if he's willing and I can't imagine he wouldn't be. The Pulmonary Specialist said a "clean" oximeter overnight run would be sufficient to confirm success, no additional full sleep study (talk about expensive)..the oximeter overnight was so economical it is affordable even without insurance... best I can recall under $200, plus of course the visit with my Primary Care, but I was getting a physical anyway.
Thanks for the reply. Actually I am in the obese category. My avatar shows my children! My partner is 40 and has severe sleep apnea, I suppose that might be a problem for me too, I have fibromyalgia and often have sleep issues. I'm going to bring it up with my doctor when I next visit. It's not particularly worrying me, but it is annoying.
The only connection I can make to your clicking symptom don't match what we know about you: age 43 (young) and if it is you in the avatar you do not appear to be overweight.
Older people, say 65+ in my experience, suffer from spinal cord deterioration which give a intermittent (not all the time) clicking and pop in the back of the neck, not throat. Obstructive (sleep) apnea would also be suspect for the breathing problem, I think.. especially when lying down. But that problem foo is more common with senior age and overweight people.
