Yes sue225, it was prescribed to help with symptoms of LS, as I was already using the steriod dermovate, but had to recently up it to every day twice for 10 days as the 3 times a week wasnt working,the burning and itching caused alot of discomfort. Doctor hopes it may help with that, some muscle aches and waking up to go for pee every night sometimes twice per night, has been more earlier into this problem. Been taking the amitriptyline for 12 nights now, first 4 nights were great, then by 7th night started to feel quite off, they say any side effects should wear off soon, so hoping things may settle soon. Not sure if doctor wants me to carry on with tablets for a longer period or just for the 6-8weeks.
