My daughter, 10 years old, is a competitive rhythmic gymnast. Hyper-stretching of her back and legs, to the extend a normal person cannot believe, is a part of her daily training. About two weeks ago, she started to complain a back pain. The pain was associated with an "electric" burning sensation in her both legs (pinching nerve). She has been staying away from the training since then. The pain subsided somewhat, but still, the lower back is tender in touch and she cannot bend either forward or backward. I know resting is the best treatment, but I would like to know if there are any treatments she can seek to speed up the healing process.
