Yes, know what you mean about hip pain, pelvic pain and discomfort and leg pain. I agree Amitryptaline helps nerve pain and aids sleep but gives me nightmares. I take sleep tabs at night instead, they at least give me some hours of sleep before pain seeps through as they wear off.
One Gp told me to use different pain killers alternatively (not at the same time of course) as interaction can be adverse. Apparently using a different one after at least 4 - 6 hours after (check labels) can be more effective overall. I feel like a juggler, trying to fine tune my pain and symptoms as they crop up. Sometimes I leave it too long before taking pain relief and breakthrough pain occurs. Other times nothing seems to work and codeine can be constipating, so I have to remember to take Fybogel and Merbervine alongside it (any stool softener can help ie Lactalose).
I occasionally find Ibuprofen 400 is more effective, but I know anti inflammatories can be bad for your stomach lining and can cause ulcers if taken long term, so I am frugal with use of these.
You also need to consider your lifestyle and medication, for example if you take too many pain relief medications (that can make you groggy) and also take Amitryptaline or sleep tabs and drive
you could compromise your and others safety on the road. There is so much to consider in managing your symptoms and pain! Sometimes I find mindfulness meditation can help soften some of the pain but need pain relief as well.
