Grace,
I know just how you feel about being scared, god i put of my surgery for 6 years because of fear.
I had bad headaches from the rectogesic, but that was just me.
I would seriously think about trying that cream Hugh (ithurtstosit) recommended. Nfepedine i think, god i know i got that spelling wrong
He says that has helped him alot.
I would also try looking more closely at your diet - from what you have posted so far, it looks like you are not getting enough fibre in your diet.
Especially your fruit and vegies.
The first way to heal a fissure is to soften the stools and get regularity happening with BM's and maybe try a cream that relaxes the sphincter muscle, this will give the fissure a chance to heal on its own.
If it is already a chronic fissure, it is likely this approach may not work and LIS may be required.
I would recommend seeing a GP to help you find a surgeon experienced in colorectal surgery. Once you have found one go and get an inspection - and then see how you feel about it.
.. oh sorry and the answer to your Q, NO you are not a baby - you are very brave and you are looking for ways to help yourself, so i think that makes you smart
Dont worry, we have all been in your shoes - and i know it is a frightening time.. we are all here to help, and hold your hand... you can be as scared as you want, still doesnt mean your a baby

Chin up, its all gonna get better from here on in
:bom:
