The absolute BEST thing to take for impaction like yours - is Cascara Sagrada. It stimulates the long muscles in the colon to work in a wave-like action which will loosen and "push off" of the colon wall.
This is why it is included in the HUMACLEANSE. You will need a larger dose of cascara over a 10-14 day period.
You should be able to find pure cascara sagrada in a local herb shop or health food store. Make sure it has nothing else in it and that it has been aged for at least 2 years - but not over 4 years. (Fresh cascara is used as a purgative - too strong! Aged for at least 2 years weakens it a bit for colon cleansing use. Bark over 4 years old is too weak for what you need.)
If you can't find any - let me know - I have some quality bark here.
Once you have taken it for a week or two - get back in touch and I will try to help you further. You might can then do a psyllium based colon cleanser - we will have to see. Right now - the psyllium will make things worse - not better.
These types of impactions CAN be moved out - but not with regular laxatives - this is because regular laxatives draw water - you need something to push off the mass.
