A slight blockage caused by an inflammed "i" valve which connects the small intestine to the large can cause such symptoms. See a gastroenterologist.
wishing you the best
Hi Falahi and welcome to the forum.
Things to look into are:
Osteoarthritis, Osteoporosis, Hypothyroidism (please read some of my recent replies here in regards to thyroid function),adrenal fatigue, underlying pathogenic infectious conditions (search here for Dr. Garth Nicolson, the world's top expert in this field) which are linked to various forms of arthritis,CFS, fibromyalgia & other serious conditions.
Another area of concern would be unresolved traumatic and emotional issues/events from the past- something like PTSD.
If this resonates with you at all, please let me know and I can offer you
some suggestions, as I'm fairly knowledgeable in this.
Finally look into Tension Myositis Syndrome (TMS) in regards to the way the brain perceives and "handles" pain.
The top expert in this is Doctor Sarno (research and treatment).
If interested, I can send you a link for a free 2 Hour lecture of Dr Sarno.
Very educational, to say the least.
Note that the above is not intended as a substitute for medical advice.
Wishing you well.
