The following is a response I sent to another post, for someone suffering severe hemohoidal pain from diarhea. Som of the suggestions my help.
Your hemorhoids sound miserable. I can relate, but probably not as regularly as yours sound. The flair ups I experience come in two forms; after being irritated by a BM, or just prior to a BM (they seem tied to the nerves that trigger elimination, just a defective version of the function). Based on that, your diahrea would increase the number of flair-ups, and with little opportunity for healing your pain is constant.
Because of my constipation I gain the benefit of having a few days for healing should I need it (good for the hemorhoids, bad for my colon), when I do have a BM I alway lubricate to minimize irritation. For flair-up from straining or a slow coming BM I use a series of home remedies.
If you can catch a break from the diarhea (without creating constipation) that could buy you some healing time. Using a salve prior to a BM could help protect the surface from the acid burn of the diarhea. I would suggest a salve over a cream for better potection.
Hemorhoids are an inflammation, that, in part, equals heat and of course swelling, so anything that cools and minimized the swelling can provide relief.
Like an inflammation from an injury, when possible, I raise it (I am not shy about slumping over a bed or couch with my butt in the air, at the very least lie on your stomach rather than sit, and no seat-donuts they can actually increase the swelling). If I have to work I stand at my desk rather than sit (tell people your back is bothering you). I will apply a salve (hydrocortisone is an obvious choice, I also use some other cooling type salves). For fast acting relief I will apply an ice pack (easiest if applied with your butt up, but I have a few I use for when the flair up happens at bed time. Or step in the shower and run as cold water as you can bear at the target; it cleans and cools.
Cool air is very helpful, so loose clothes (or no clothes, if an option, especially warm summer nights). I sleep with a small pillow between my knees to minimize the heat from my thighs adding to the problem). Sit on chairs that breath (mesh seating is way better than the cushiony leather or vinyl seats).
This all sounds intense, but really you find a few thing that work for you or you rotate the remedies as the need presents itself. I am an experimentor by nature so I'll try anything once, and I now have a grab bag of options. Now I am getting serious about getting rid of them altogether.
I really think one of the first areas you should focus on is diminishing your diarhea. Again with caution toward avoiding constipation, try food that would decrease the acid by limiting acidic food, eat cooling food such as raw vegies, cool drinks, dairy products would probably be helpful, you can probably do well with beans (odd as it may seem). All of these of just ideas, don't take them verbatum. Check out the cookbook I suggested for some direction, and seek professional assistance if possible.
My wife is acidic, I am alkaline. She is working to cut down her acid, I take hydrochloric acid pills. She can eat almost anything and it moves pretty easily through her (sometimes like you, too easily) I have difficulty digesting a variety of things so things get stuck. So keep looking to find out where you fit.
Good luck! I'll be watching for updates.
An additional note I would add for those holding off on any type of surgery would be; resolving the cause of your hemorhoids first (if an option) will minimize problems after the surgery. I began to seriously consider surgery about two years ago (after having hemerhoids for almost 3 decades). I chose to focus first on my constipation which is the primary cause of my (too much straining). I would be fearfull of ruining the benefits of surgery by straining from continued constipation.
I have learned so much in two years, I think I'll start my life over now (oh if that were only an option). I have decreased the occurance and severity of my hemorhoids (although my rectal prolapse is another issue) and I have improved my overall digestive process, slowly diminishing my constipation. With guidance from my natural care doctor I have increased the amount of oils I eat (mostly sesame seed oil, also flax, cod liver D, and olive oil) to 6-10 tablespoons per day (in meals). After several months I have only felt improvement, and my stools, even when firm, pass with much more ease (this is not necessarily recommended for anyone with diarhea issues). Fiber, as we know, is important, but for certain body types like mine, it can be hell. After healing my IBS I have been able to reintroduce some fibers with little to no gas and cramping (ground flax, apple pectin, some psylium - but cautiously). A oils/fiber/water combination is key componants to a naturally healthy stool (dry fiberous stools are like sand paper on the intestinal walls). It is a key part but not a cure in and of itself, but I can't write a book here (if you've caught any of my other posts, you might contest that...yeah, I get a little wordy).
Hope this helps someone out there. I see three other similar posts today, so I think I'll copy it there as well. So, sorry for being repetitive.
Good health to all!
