From history your both complains seems to be different.
Having lump in your testicle might be due to having epididimo-orchitis.
For that consult sexologist
and get examined.
Having blood in stool
, as it is bright red might be due to having internal hemorrhoids
But as you are 51 years, passing blood in stool requires evaluation.
Consult surgeon and get examined.
Take plenty of water.
Avoid fried and junk food.
Ok and take care.
