You are very welcome Canadabum! As for this:
"but I am interested in understanding....if we keep it soft and dont challenge the sphincter and passage to open up more will we somehow be damaging our ability to keep the passage flexible and able to open once the fissure is cured/gone?"
My physios answer to this is a resounding YES! I will ask my CRS but I suspect he will say the same. The trick is to get the muscle to stretch in a controlled manner first, like with a finger and work up to dilators. This is my plan anyway. Then, when it is able to open more, one can make the stool less soft.
As for the Doctor's cancellation list, depending on the office, I often found that calling once a week or so is more effective as I think they are often too busy to look for the list and call people. Have gotten in sooner that way a few times. Of course it depends on the office staff as some may be annoyed by this, others don't seem to care and some even seem to think you are doing them a favour, which you probably are if you happen to luck out.
I take a lot of magnesium, let's see...150mg with supper and 200mg before bed with a product called Magsense (also has malic acid - this gets the bowels moving) which may also give another 100mg. I need it almost watery at this point
Glad to hear you are feeling better. On you bike! That's awesome! That is a goal of mine. Even my grannie-seat exercise bike in the basement will do for now...can't wait (how sad is that?)!
As for the diltiazem, what about nifedipine instead? I find it the least irritating of the 3. Even if you are feeling better it might be good to have on hand.
