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
