Wow! Just how many of YOU have had swelling of feet and legs from the drug NEURONTIN?

I have Sjogren's, Lupus and Fibromyalgia among others, all in the auto-immune family so anthing regarding these diseases always catches my eye. It has to be interesting though because I've delt w/this stuff for 20 yrs. and I don't have time to invest in my illnesses anymore. They've robbed me of too much of my life already. But when I saw that someone had questioned the relationship of drugs to treat Fibromyalgia with SWELLING I had to look closer; much closer, because my neurologist increased my Neurontin to 400 MG twice/day. He wants to increase it more when I see him next week. Meanwhile, my nephrologist, rheumatologist and internist are all at a loss as to why my lower legs and feet are SO SWOLLEN these past few months. I'm very slender, so I'm not taxing my lower body. Could it be the NEURONTIN? I'd like to know if others have had this side effect. It may be more common than anyone knows. My neurologist really likes this drug and has no problem prescribing it in high dosages for chronic disease because of its compatibility w/other drugs and little side effects, but is SWELLING perhaps a wide-spread side effect?
