I know there has been some posts about this, but, surely someone has found a remedy by now. I am having severe cramping below the knees...(front and back) almost every night. These cramps come in 20 to 30 second cycles...and sessions last up to 20 minutes. Relax, and in an hour or so...they start up again. Family doc doesn't know...seeing pulmo next week...what field deals with this issue? (btw, I am drowning in water, and retaining, bananas, pickle juice, tonic water, magnesium tabs...tried everything I have heard about...still crampin')
