Tom two things back.
The breathing thing is something I experienced...for me it was a tightening to the neck that felt like I couldn't get air, had to sit up and readjust then lay down again...added pillows then a towel under the pillows to elevate the head.
It turned out for me to be the scalene muscles of the neck. When I lay down and gravity is removed from the picture, underlying spasm was ocurring and it felt like I couldn't breathe. Choking being strangled...tight...I would panic a bit.
I use trigger point injections for those dang muscles.
A book I have is called "FM and Myofascail Pain" a survival manual by Dr.Devin Starlanyl. 19.99 on amazon.com. Helpful to see the anatomy and the cause effect of some things.
I saw so many docs, thyroid chcks, got endoscopy...tortured me...told the neurologist and she knew right away. She pointed in "Travelle and Simmons" the neuro book of the anatomy of the body...BOUGHT that book too. Read it, dry reading....underlined and highlighted as it was the fist time I had something to hold on to...of WHY DO I FEEL LIKE THIS.
Now there are other situations that can cause this symptom so be sure to be checked well. We tend to blame the dragon for everything but it may not be that.
The other....benign node enlargement of that area can be blocked salivary glands. ENT can look into that for you. be sure it is lymph nodes.. they can also see other causes. Please use a large facility center for the specialist..or someone highly recommended by the public or your doctor.
A YEAR...you have had this a year? Has a work up been done? OK, that's my two..I have to get to work...see you tonight, I will look to see what you added. Good luck, Nancy B
Try warming your neck before you lay down to help....(you are not obese and have a tight belt when you bend over right??)(Just asking??)............Nancy B
