I'm very sorry for you and your daughter. Being powerless to help one's child must be one of the hardest things for a person to endure.
It sounds like 'diabetic neuropathy' is behind the horrible pain she has been experiencing; I don't know if very tight control of her sugars would make a significant difference in progression at this point, or if once the damage has been done, the progression is inevitable-- that might be something to ask her endocrinologists. Lyrica is similar to a generic medication, gabapentin-- again, something that might be helpful if cost becomes an issue or if the insurer gives you trouble with the Lyrica.
There are more aggressive treatments for chronic pain, including spinal cord stimulation. I would consider that an option of 'last resort' though given her likely vulnerability to infections.
Sometimes a small dose of an opiate is helpful for neuropathic pain; because of tolerance, you don't want to get into a situation of repeatedly raising the dose... but simply staying on a low dose of a potent opiate will add a small degree of comfort that is different from the type of relief she gets from the lyrica.
Finally, travelling the world would not likely help, as we have some good options near by. But I would seek out a University setting and obtain consultation there periodically, if you are not doing that already-- just to be sure that her care is keeping up with the changes in medical options.
Take care, both of you,
JJ
Thankyou for your reply, at this moment she is under the care of her edocrinologist in hospital and they are getting a neuroligist to have a look at her with faith there may be some help for her as they are talking options so far Ive only heard from what my daughter had to tell me as I am at work during the hours doctors come to see the patients. But ill write what you suggested down and tell her to give it the doctors. Thanks again for your help.
