Chronic pain is exhausting. I tried LdN for chronic migraine and it did not help. My daughter uses it for Chron's and it helps her. Since it has to be compounded, there can be a huge difference in price from one company to another. One place was charging me $65 for 30 tablets and my husband had to pick it up. Then my daughter told me about another company she uses. Three months of tablets and they ship for I think it was $67. They were slow to refill so I just needed to pay attention and order in plenty of time so I didn't run out.
