Dear Customer, Thanks for providing quick additional information.
I'm so sorry to hear of your discomfort.
These symptoms are suggestive of a medical condition-
Intestine parasite infection. It can occur due to Amebiasis caused by parasite Entamoeba histolytica.
Having loose stools, pain in lower stomach, backache is due to such infection.
Pounding heart may come due to infection or flu. This may also come due to anxiety and get resolve when symptoms are resolved.
Usually this infection is transmitted when someone comes in contact with infected feces through contaminated food, or water.
To make a diagnose, a stool culture test and a complete blood count test has to be done.
The most common prescription anti-parasitic drugs are-
-sulfametoxazol (can be used for cyclospora), tinidazole, metronidazole, praziquantel (for tapeworms).
You should take probiotics 1-2 times a day between meals. Appropriate antibiotic will be selected after stool culture test.
You should Keep yourself hydrated, and maintain fluid levels.
