text: pain on the side of leg? i had this pain on the side of my leg it is not as bad as it used to be because i dont run in gym class any more. it has not hurt in some time but i know it is a step away from it starting all over again. it is on the left leg on side of the side not on the calf or the sheen but on the side when it would hurt it would feel like a burn. it is not a sheen split when i whent to the doc he took a x-ray and he could not tell it looked like a bump on the bone he said it could be a small tumor but he is not suer. he told me to get an mri but the mri i was cancelled what do ou think it is what might happen if i dont find out what is wrong with me. it is probably a harmless osteochondroma. an mri can tell this, but also rule out a life and limb threatening osteosarcoma - this cancer can be deadly. even though you are probably fine you need to follow through with the mri as soon as possible. get it rescheduled!
