I have had similar issues, all linked to anxiety/stress and work. I posted this same reply in another topic, which was related to not getting a deep breath. Ive had alot of the symptoms that are posted by my fellow anxieters, so hopefully someone gets relief from my suggestions.
One question everyone in this forum should ask them selves, do you work in front of a computer? I have done so for years and these issues on started after a few years of working in front of the computer.
Some things that help me to "release" so that I can breath deeply and get rid of my throat lump feeling are:
1. Hot water bottle
2. A good physio therapist (preferably sports) as they seem to understand muscles and how they operate in your body
3. Beleive your doctor, I know its hard but you have to have faith in them or if not one, get a second opinion, dont tell the second one at all that you have seen another doctor, so then their decision is not biased.
4. In australia we have bowen therapy, not sure if you have it over there, can be very effective.
5. Yoga or pilates
6. Work less, or take more breaks.
7. Review your matress, you spend 1/3rd of your life on your bed, and it may not be as "supporting" as it used to be so could be causing back issues which cause back spasms/tightness
8. Laugh as often as you can, if not at a comedy, ring an old friend and reminise over stupid things youd do, its amazing how much laughter helps.
9. Ride a bike
10. Get a massage
those things have helped me, ive had some rough trots, but have gotten through them. One thing which I always would think to myself when I thought it was the worst its ever been was, what doesnt kill us makes us stronger.
I even went to the allegist, as I thought it must be some sort of allergy to a food, it came back that I am allergic to nothing. This may surprise you, but the allergist said, he has had some worse off ppl than me, that were only eating rice and water. He said he referred them to a speech pathologist? You might be thinking yeah right sure that works, but the speech pathologist can give you exersizes to release the muscles in your throat, which give you relief from your symptoms, and will allow you to manage them. Further to this the exersizes allow you to learn open throat breathing.
Typically with my issues, I have found they occur due to muscle spasms or tightness in my neck/back and between my shoulder blades.
Hope this helps.
