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 stress/ anxiety, mild GI infections, inflammations, GI motility issues, hormonal/ endocrine causes, medication side effect, connective tissue disorders, growths/ masses, micronutrient deficiencies, metabolic/ electrolyte issue etc. Without a definite diagnosis at hand it would be difficult to suggest a management plan. I would suggest getting this evaluated by a primary care physician or a gastroenterologist for an accurate diagnosis and appropriate management.
Hope this is helpful.
