Today after having the bowel movement, withing a span of 5-10 minutes i started having slight heaviness in right lower abdomen and then i had an anxiety, right nose blocked feeling and little breathing issue (actually i can take deep breath also) but suddenly breathing issue, that i also do not know whether it is anxiety or breathing issue. Mostly i have seen after clearing bowel, this type of heaviness occurs and disturbs my whole day. I was on a medication for gas trouble, eat Pan-D capsule before food. But still i am having heaviness. I am a 25 years old, my weight is 65-68 KG, i am not physically active.
