Lumps on heel bulbs

[South Dakota]

Has anyone else seen anything like this before? Can’t find any info/pictures anywhere. These ‘lumps’ appeared pretty much overnight on horses hind heel bulbs. Both feet affected. Soft and squishy for a better word not painful. Vet advised they think just top layer of skin has “eroded” away pos due to bacteria/wet ground so have dispensed some blue spray (Terramycin). 2 weeks on and no difference to be honest- will be speaking to vets again Monday. Horse lives out 24/7 with no option of stables. Anyone have any advice? Thanks

Wet ground! This went away but horse was stabled overnight to dry out. I just sprayed with stuff (can't remember what, generic hoof spray/purple spray type stuff) and it sorted eventually. It had just been raining constantly and the ground was wet as you like for weeks and weeks.

Yup, looks exactly like my white footed horse got this summer. Sudocreme sorted it out. I came to the conclusion it was fungal as it stopped as soon as the weather cooled even though it was still damp.

Thank you both so much.
