Hi and thanks for the query,
It is possible that the sudden change in atmospheric pressure when you jumped 50 feet may have injured your ear.
There is a tube that connects the nose to the ear from the inside.
This tube is supposed to maintain atmospheric pressure inside the ear. It tends to malfunction when there is a sudden cahnge in pressure , leading to either a fall or rise in pressure in the ear, inturn causing damage to the ear.
You need to see an ENT to know the extent of damage.
Till then you can use any nasal decongestant drops like otrivin
which will reopen the tubes and equalise pressure once again.
Instill 3 drops of otrivin in both nostrils 3 times a day and follow it up with steam inhalation for 5 days.
