For As Long As I Can Remember I Have Had

For as long as I can remember I have had pains in my calves like knots and cramping. I exercise pretty regularly and about a year ago I started getting pains like knots in my thighs and my left hip side and buttock. The pain in the left hip side is so bad sometimes the first few steps I can barely move. I use rollers and things to keep messaging the muscles and stretching but the pain never goes away
