Another cause of this is using laptop in bed on your side for long periods stop that ASAP as well. But I think most will have asymmetry of shoulder, forward neck position and rounded shoulders.
As soon as I retract shoulders down and back relief could come quickly. Let me know how u all go?
Also when I press the sore rhomboid muscle the referral feels inside the Adam's apple. The greater horn of the hyoid is tender from asymmetry and i think it's scraping the submandibular gland irritating it and/or pressing rhomboid causes salivation which feels like its inside throat why when ent checked mine all ok. So check your shoulder hights and poke around to find your rhomboid
Also check your T spine it's probably inflexible from too much laptop and or bike riding. This is a posture problem in most cases. Took ages to work out saw so many doctors who had no clue but finally worked it out. Reflux is probably due to stress and or asymmetry of shoulder and neck. Neck tucks may be useful too. U may have cervical lordosis but look at your shoulders if one higher then other and if tucked back and down properly. Get a physio to strap them in correct position few days and start doing back exercises and stop all chest exercises
This is the problem I think
1 u have rounded shoulders weak back muscles
2 u have sore rhomboid muscle or one shoulder blade sore
When press rhomboid which is inflamed it refers up to the head and Into the Adam's apple
The shoulder ( check them one might be higher then other) is pulling your strap muscles to the left or right putting the cartilage crooked a bit and irritating it and making it click, why rhomboid is sore
So
Keep your shoulder back and chin tucked in when walk or sit with straight back
Go to gym do back exercises lateral pull down, seated row, dumbbell fly, assisted chin up
Do rhomboid stretches and chest stretches
Get back massaged by physio and posture fixed
Stop using laptop with forward head position
Sleep on back with towel down spine or sleep on shoulder which doesn't have the sore rhomboid muscle
Relax!!!! Stop worrying it will get better
This is a posture and weak back problem I think get your back checked by a physio and see if fixes the problem it's due to asymmetry
I don't think the crunches\clicks when you press on the right are anything "broken". I think it's something out of alignment and that crunching is cartilage rubbing.
