Wow...that's a lot of possibilities....now it's been 9 days, with exactly the same symptom, only when I wake up from sleep and then disappears. At a friend's suggestion, who is a nurse, I took advil to see if it was inflammation, but there was no change. Thanks for your response.
Hi there!
Well, without a detailed clinical evaluation it would be difficult to determine the cause of your symptoms. Possible causes that may need to be considered include GI infections, inflammations, gastritis, GERD, GI motility issues, dietary causes, neuro-muscular causes, chest wall inflammation, costochondritis, hormonal/ endocrine issues, micronutrient deficiencies, growths/ masses etc. I would suggest getting this evaluated by a primary care physician initially and depending on the cause diagnosed/ suspected, it can be managed accordingly or specialist care may be sought.
Hope this is helpful.
Take care!
