After reading quite a few threads here, and reading up on line, I have found a twist that seems to work for me.
I think that there is much information about regular baths and sitz baths helping. Well I really agree with this - it has made me heal and has help alleviate the symptoms.
However I also found an additional method - the hot water bottle.
I found it hard to plan to have a sitz bath at work - it just didnt feel right. However I did find that I could take a very small hot water bottle, fill it and sit on it twice during the day. It is really discrete and not obvious that you are doing it. When people did ask why I was filling a hot water bottle, I said I had pulled a muscle.
Additionally I have found that if I sit on a hot water bottle after a BM it dramatically eases the after effect pains - totally for me. Also I found that if I sat on a hot water bottle about 10 mins BEFORE a BM my muscle was much more relaxed and I could go much easier.
I would be interested if anyone else has done this - and if anyone knows of any reasons why I should not be doing this! Cheers!
