Twisted back awkwardly and it cracked twice, now in agony and have sharp pains all up my spine is this normal? i'm only 18 and play a lot of sport

Back pain: Being young and fit, you have unlikely caused any serious damage. The awkward twisting likely resulted in a strain/sprain type injury of the spine. A serious injury would produce persistent numbness, tingling, or weakness in the legs, bowel or bladder dysfunction, or groin numbness. Recommend low impact activity, ibuprofen, heat/ice. If symptoms persist over 7-10 days, seek formal medical care
