Sorry for the late reply and inconvenience.
Thanks for all this additional information.
I understand your concern.
And it’s my first privilege to pay attention and provide you with suggestions to relieve your discomfort/ worry.
Well as you describe, it sounds like bruised ribs/ Costochondritis.
And it may take some time to heal.
You should avoid any undue stretching.
Also, avoid tight garments.
Icing the area regularly can help with healing and pain relief. You can also use a hot water bag to ease your pain and discomfort.
See your doctor again for prescribing strong pain killers and may also advise respiratory therapy. You’ll learn breathing techniques that can reduce some of the pain, while still allowing you to fill your lungs with air.
Hope I have been able to clarify the situation for you and helped in resolving your query.
Let me know if you have any further queries so we can discuss it thoroughly in every aspect.
It’s my pleasure to continue this conversation until you satisfy.
Waiting for your response.
