So i every now and then get really bad leg pains, usually in only one of my legs, very rarely both. It varies and can be from my toes to my calf, up my thighs or my whole leg, sometimes its around my knee, sometimes around my ankle, it can basically be just anywhere on my leg. It feels like a strong dull aching in my bones almost. Sometimes i wake up with it, sometimes it comes during the day, it doesn't seem to be connected to any kind of physical activity. Theres no swelling , warmth or redness when it happens. I've been to a doctor about it but they werent much help, i got stretching exercises (that didn't help), then I was told that they couldnt do anything. Im often told its growing pains, but i am almost 18 and haven't grown an inch since i was 13 (i measure myself frequently). Does anybody have any suggestions as to what this could be??
