Brief Answer:
Blood in stool is not related to taking Aloe juice

Detailed Answer:
Hi

After going through the entire description, it seems that your major concern is blood in stool and back problems.

As blood is very pink in colour, it seems fresh blood. It is probably due to injury to anal region by hard stool. It may also be due to hemorrhoids. This can be confirmed only after a physical examination by a general surgeon or a proctologist. For the time being, you can continue doing your regular activities including going to the loo. It might bleed a little. You are right in using a pad. But, please make sure that you visit a doctor.

Develop a water addiction because dehydration can exacerbate constipation.
Consume extra fiber and enzymes from fresh fruits and vegetables.
Get up and move. Sedentary habits make things settle and motion keeps things moving.

Try acupuncture, or massage therapy for your back pain.
You must avoid any activity that aggravates the condition, like bending forward and lifting heavy objects, sitting long hours on computer, inappropriate sitting posture, etc.

Thanks for consulting me. Hope I had been able to address your concerns. Let me know if I could be of further assistance.

Wish you good health. Take care.
