Lyrica
"I devolved severe sciatic leg pain about 3 years ago after damaging my spine.  I was bedridden for two months. My doctor here in South Australia tried different medications including morphine pain patches and oxycontin which did slightly help. I had two cortisone injection in my lower spine which worked,  the pain went. Yeah  4 weeks later, I developed severe chronic peripheral neuropathy i.e. muscle leg cramps.  I started out on 150 mg Lyrica and now 300mg. The Lyrica makes me tired so I do not drive unless I stop taking it the day before. My wife massages my legs for 15 mins morning and night. I use a tens machine plus a Revertive foot machine for relief."
