I took a number of pills last month. this month i'm having numbness in hands when sleeping. i had one red stool but others were fine. little constipation. what could be wrong? the numbness goes away after waking. also had covid?

You don't mention what types of meds you took last.month. Since your hand numbness resolves after sleeping, it appears to be positional during sleep when wrists are bent. If the blood was a tiny amount on toilet paper only, it was most likely a benign issue like a small anal fissure or hemorrhoid. Large amounts of red blood require investigation though.
