Yes please I am concerned about your problems and it may probably be due to agni dusti as per ayurveda view your agni is not in a balanced state so these problems are arising to you and so there is no proper pachan i.e. digestion of food, leading to formation of aam(toxins) in your body that is leading to the above complaints you have told.
So I suggest getting a proper consultation from an Ayurvedic doctor for your concern, as you mentioned that your all reports are normal.
Next Steps

Health Tips
