肚瀉,希望有醫護人員幫我解答(20分)

很抱歉，我並非醫護人員，但我相信以下的方法一定可幫到你的。中藥蒼述、砂仁，前藥兩味等份量研粉沖服，立止瀉。另外我建議你買一瓶名叫川貝枇杷膏，回家後用溫滾水沖服，每天一至兩次—可幫助身體消化與吸收，改善身體內的多餘物排出。

Usually for 肚瀉<2weeks it is due to infective causes, since you don't have it anymore, it is likely to be the cause.

肛門口有一點點脹感,有點點想如廁的感覺: is called tenesmus in medical terms: which describes the feeling of wanting to go to the toilet even right after defecating.
Infection like gastroenteritis can cause tenesmus
I too am not too sure about the actual problem, but i believe it would subside on it's own, there is no need to worry.

if anything changes or worsens you can always see your doctor then, it is nothing serious at this point in time.
