Hello Good Evening,
This might be seems a fracture
of your toe.
According to your history you jumped on to the ground, so there was a strong voluntary force applied by hard surface of the ground f/b unbearable pain and swelling.
So there can be a fracture along with tendon injury
and edema, which is causing pain, tenderness and swelling at that site right after.
Fracture needs to be managed by immobilization, like with a POP slab, and if there is any displaced fracture, then surgery may be needed.
So now simple steps to be taken:
Just go for a x-ray foot.
Go to orthopedic doctor for further management.
