Can a person be diagnosed with crps without the sensitivity of touch? they can still wear long pants touching their legs but they have burning in leg

Yes, maybe it's good: Young people often can recover and that touch doesn't hurt might be a good sign. You need treatment and early is better. Here's info: http://www.ninds.nih.gov/disorders/reflex_sympathetic_dystrophy/detail_reflex_sympathetic_dystrophy.htm Find a good treatment facility and follow recommendations. It's not simple, but you might do well. Best wishes!
