Just keep it cool and you should be fine!

I kept mine in the bathroom ( both Nitro and Nefid. ) - had no problems with that.
Tabby LOL - if it ever comes to the point of me giving massage to my anus - please lock me away

Fiss, its no laughing matter seriously, a nice massage
The things you do !

I used my diltiazem for months and just rubbed it in, I dont think I could have stood the pain of putting it inside! It still worked brilliantly though, and our instructions on our tubes here in the UK says to rub it in, not put it inside.

"TUbby" ; ) - I know LOL, we all do stuff that to other people would look bizarre and probably even perverse LOL- but hey- they do not have defective exhaust pipes !!!
Val - how are you doing buddy ???!!! I hope that all is great on all fronts : )) !!!! How is your derriиre behaving lately ? I hope that it healed completely !!! Keep us posted about baby !!!! You know that we all here are eager to know and are praying for you both !!!
LOVE TO ALL

I know Fiss ! Hoping you are well today :'\;redbud:
My instructions say differently Val , Maybe its a scottish thing !
Hope you are well too dear Val

Uh oh!
Is burning a normal side-effect of diltiazem? I'm experiencing (rectal, obviously) burning after applying the cream (internally and externally). Should I be worried, or is this just a side-effect I'll have to get used to?

I think that I had some burning when I first started using it, but as my fissure has improved, I don't have much burning now.

Some people have that as a side effect - that is because your capillaries are dilating to promote blood flow which in return help fissure to heal. Burning should stop as soon as you stop using the cream though. If it is terribly annoying you can try other creams.
All the best !
