Hi fq,
I know EXACTLY how you feel in terms of the throbbing rectal/anal pain. I actually just spoke to the nurse about this same issue on Monday. She basically told me that my system is in overdrive right now. I had gone off the pain meds (which slow things down considerably) and had not started to take any immodium yet for fear of blockages (as I was still a bit swollen from takedown). She suggested I begin taking immodium 1/2 hour before each meal. She also refilled my pain med script (vicodin), which I am fine on if I take it in moderation. Things have already started to get better. I go less, so there is less irritation/inflammation in the area. The goal is to slow it down enough to get to a point where I can start stepping down the pain meds once again. It is a process, but patience, persistence, and the right mix of meds and advice can go a long way.
I would suggest you call and talk to someone in your surgeons office. The soaks in the tub do help, but that is only a temporary measure. As are the creams. You need to get the inflammation, caused by going so much, to subside so you can heal. Also, it might be wise to rule out any other issue that could be going on, such as a stricture. I have never had one, but know they can be very troublesome judging from posts on this site.
Hope you feel better soon!
