Sculpting, mesh collapses into itself when i edit one side?

this has happened to me a few times but i wanted to find a way to fix this problem
im Scultping an animal head and i wanted to make the ears bigger then what i originally had. When i use the infalte took ( or any tool for that matter) the mesh seems to collasp onto itsself and dosnt add any volume. Is there a way where i can fix this?

This is after i use the inflate tool, beacuse im a new member i cant post an image of what it looks like before, just know its not this lmao
