<s>[INST] I broke my left calcareous on Friday 8/14. I was put in a splint fromED and air cast Monday 8/18. Overnight and throughout the day today while wearing the air cast I am experiencing numbness & tingling in mycotoxins, ankle and toes. I have loosened the compression straps as much as possible. I only feel relief when I remove it. Is this normal ? [/INST] Hi welcome  to HCM I can understand your concern regarding tingling after wearing air cast? Your nerves numbness is a common condition that can be caused by vitamin B12 deficiency, injured nerves or sitting is the same position for a long time .When your bandaging is too tight creating numbness and uneasiness  for you by hamperring the process of circulation  this is why it felt better when you loosened the compression straps blood circulation to your ankle & toes  which needs blood to heal .And include  proper nutrition - Vitamins , minerals , and  also slow activity can help mobility and strength to recover fast . So , If you feel relief by loosening  the compression straps , apprise your your doctor of the situation  If you have any concerns, don’t hesitate to call a doctor .Hope this helps solves your query .Take care , All the best .Don't hesitate to get back if have any further query </s>
