so i have this bump on my foot.(its not very big, but definately not small) its located on the side of my heel. not on the bottom(just so you know its not a heel spur) its too far on the outside. it hurts very badly in my whole heel when i step on it, and after i run it pulses. the pain makes my outside ankle ball swell and it also kinda swells on the front of my foot, where my foot meets my ankle and it sends pains up the outside of my leg and it has a little swelling there too.
if you have any idea please help/

p.s

when you put pressure on the bump it hurts veryyyy badly!
