Thanks everyone.
OzJo - Sorry I should have given more background. This is my second child, with the first I was very open to pain relief! I have pethidine and an epidural, I used tens too. The pethidine (for me) was dreadful, slowed me down, paralysed my right hand side, and I felt constantly sick.
The epidural was lovely - a little too lovely. My memories of the hours post-birth are very very blurred. Also, had to have the catheter, episiotomy ventouse etc.
The tens was crap, just like gnats biting at my back!
I am open to an epidural or similar if I need one. But I want to avoid it - plus I know as most second labours are shorter, I may not have the chance.
So, rescue rememdy for panic, arnica for the bruising, caulophyllum to strengthen contractions, mur for back pain, kali. phos for exhaustion, acontite for stress....
Will look at online kits!
