I’ve recently been prescribed Lyrica for Fibromyalgia, after taking it for 1.5 weeks, I experienced major swelling, especially in feet in legs; therefore, I’ve stopped taking the medication as prescribed.

Yesterday I was having sharp nerve pain in hip, with nothing else to take, I took one capsule before bedtime and the pain has subsided. Will this medication work on an "as needed" basis or does it need to build up in your system?
