What Causes Leg Cramps While On Simvastatin And Zyrtec?

What are the causes of my severe inner thigh leg cramps. Both legs but never at the same time and always during the night . Also , my lower legs are so sore that it was painful for me to walk through simple brush when I went hunting this past weekend . It s hard to lift them over same things. I have bad needs but this pain is not my knees , it feels muscular not bone related. I was told by a DO s nurse that pickles help, someone else said drink tonic water for the quinine, and I the melocam for inflammation along with Tylenol for pain . I have a topical cream like Ben-gay for my doctor at the va. I take simvastine for cholesterol, 10mg every other day. Zyrtec and nasalcort and meloxacan for allergies. Do Hylands leg cramp pills work . Would a steam room or whirlpool or light exercise help.? Please advise
