Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, you should definitely
consult doctor and get done
x ray of both ankle and chest to rule out internal pathology.
Jumping down from height cause pressure on feet bones and ligaments.
In some cases sudden jerk can also damage lungs.
So get done chest x ray and ankle x rays.
If they are normal then no need to worry much.
Apply warm water pad on affected areas of ankle and chest.
Take painkiller and anti inflammatory drugs like
ibuprofen or
acetaminophen.
Don't worry, you will be alright with all these.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
