In Paget's disease, something makes the bone growth process go awry in one or more bones. The result is bone that is thicker, though more brittle, than normal. The condition usually shows up as a chance finding on an X-ray done for some other purpose. About 10 percent of people with Paget's have bone pain or joint pain similar to that from arthritis. To treat bone pain from Paget's, people can use pain medication such as acetaminophen, aspirin, ibuprofen, naproxen or other anti-inflammation pain relievers available by prescription.
Synthetic calcitonin is available by injection.
In all likelihood, you're putting pressure on the sciatic nerve, a large nerve that comes from your spine and travels down your leg. That's why it's hard to walk after letting this go on for too long. Similar symptoms can happen if you fall asleep on your arm. As you might imagine, treating and preventing this problem is as simple as keeping pressure off the affected nerve. Change your position, and make sure there's nothing in your clothing or what you're sitting on adding to the problem.
