Can someone tell me if the 3% solution will accomplish alot in the system to heal it or does it have to be the 35% solution to do a much better job.

I soaked in a tub of 3% last nite (used 1 1/2 bottles)
I really did not notice any real difference, but the tops of my feet were incredibly itchy afterwards and my right achilles heel itched alot as well and alot of dead skin came off.

Also do you pour it all in before you get in the tub or do you pour it in at 5 min. intervals during bathing?
Which method would accomplish the most healing.

I did read that you should hop in the tub first an allow the hot water to open your pores first before adding the H202.
Maybe i should try that.

Thanks
