Thanks for writing in.
The possibilities I can think of are Viral Fever
, blood loss, or anxiety
due to witnessing blood from the anus, low blood sugars. All these conditions can cause cold
hands and feet, shaking, nausea
You did the right thing by giving him a tylenol
for the fever. However, I would advise you to take your friend to a doctor and get the following blood tests like random blood sugar, complete blood picture etc. Probably the bleeding(fresh red blood|) from the anus might be due to piles/ anal fissures which also needs to be evaluated.
In the meantime, see how he is responding to tylenol. If he is feeling slightly better, it might be an indication that he might be having viral fever. Please document the temperature reading. Viral fever normally present with temp more than 101 F. The treatment is usually symptomatic with tylenol 3 times a day for 2 days, and hydration. Make sure he is well hydrated with plenty of warm fluids to drink.; warm water, warm milk, warm tea etc....
Wishing your friend a speedy recovery.
