Detailed Answer:
Hi

Thank you for asking HCM

I have gone through your query. Your breathing problem can be due allergy from acid reflux. Gastric problem can give acid reflux and which can irritate throat and give allergic problems. This can give breathing problems. This is usually found in many people. Veloz D daily and mucaine gel wil be helpful to control the gastric problems. If still you getting breathing problems then antihistamines like cetirizine (Zyrtec) once daily will be helpful. This you can get over the counter.
For neck and back problem sleep on hard mattress. Use orthopaedic pillows for neck. Keep a pillow under knees also.
If the condition persist then a consultation with chest physician, chest x ray and spirometry test should be done.

Let me know if anything not clear.
I am happy to help you.
Thanks.

Brief Answer:
Cervical spondylosis can be the possible reason.

Detailed Answer:
Welcome again.

Thank you for your follow up query.

Cervical spondylosis can be the possible reason for neck pain which gives radicular pain to hands and chest. This is due to nerve root irritation or compression by cervical spondylosis.

Muscle relaxants like cyclobenzaprine , neurotropic drugs like pregabalin and physiotherapy will be helpful for this. X ray of cervical spine should be done to rule out this. A consultation with orthopedician is well appreciated also. Physiotherapy like TENS and massage will be beneficial for this. You can also use othopedic pilow for neck while sleeping and sitting. Sleep on hard mattress. You can also wear a soft cevical collar. These all measures will help to recover from this.
