my 27 yr old daughter has knots along some muscles in her legs. ankle area, quads, i t bands. she walks a lot drinks lots of water, doesn t use a lot of salt. they are painful to the touch and hurt when she walks on some muscles. she can feel them along muscles, some are reddish in color, and have almost bruised swelling around. she had these before several yrs ago, but went away be the time she was able to get into see a dr. I m thinking she needs to get in and get them seen thru ultra sound (x ray won t see)
