Welcome to HCM
We understand your concerns
I went through your problem description. Quite normal and natural. You were standing in a queue for some time which caused your lower torso go numb. The tired feeling out of that contributed to bowel movement, which is not uncommon. Definitely you felt better after water, which is the best option to do. sweating and the evacuation visits are out of your anxiety
. Still if you are in doubt, please visit a general physician and confirm.
Hope this clarifies your doubt. Available for further clarification.
