Hello!
Welcome and thank you for asking on HCM!
I understand your concern, and would explain that it is necessary to perform a comprehensive differential diagnosis of different disorder affecting the chest structures (lungs, cervical column, 
acute coronary syndrome, aorta). 
I would recommend consulting with your GP for a careful physical examinantion, a chest x ray, a resting ECG, respiratory function tests and some blood lab tests: 
- complete blood count
- 
thyroid hormone levels
- 
cortisol plasma levels (adrenal gland function)
- PCR and sedimentation rate
- fasting glucose
- blood electrolytes, 
- kidney and liver function tests, etc. 
It is necessary to perform a 
cervical spine xray , possibly followed by a cervical spine MRI if suspicions about a cervical disk displacement are raised. 
If all the above tests result normal, I would advise to perform the 24 hour urinary levels for metanephrines to investigate for a possible 
pheochromocytoma, which may be the cause of a similar clinical scenario. 
Hope to have been helpful!
Feel free to ask any other questions, whenever you need!
Best regards, 
Dr. Iliri
