<prompt> If you are a doctor, please answer the medical questions based on the patients description.I got into a car accident 2wks ago and was diagnosed with chest wall contusion. Well, I have been doing my breathing exercises but still having chest pains every now and then and its hard to breathe but I do have asthma... So, my question is how long does it take for a chest wall contusion to heal and should I be worried do I need to go to a doctor?  <response>: Respected user, hi I evaluated your query thoroughly. There are no absolute timelines for healing from chest wall contusion. It depends on multiple factors as - size, depth of contusion - presence of infection - comorbid conditions as diabetes other related issues - local care in form of cleanliness - general healing factors of patient - many more. In a nutshell small, minor contusions heal within days but if major - with infection or other conditions may take longer period. Hope this clears your query. Welcome for any further assistance better with photograph of it. Thanks for using Chat Doctor .com giving me an opportunity to assist you. Wishing you fine recovery from the same. Regards dear take care.
