For some reason there are extruded lines and points when I am in object mode on the model's left shoulder, but these lines do not show up in edit mode. I thought it might be the weighted paint but it doesn't seem the case. How do I reduce/get rid of these lines.
I seemed to have overlapped my points and duplicated them during edit mode and making them deformed in object mode.
you have hidden geometry , in edit mode press alth
Select the mesh
Go into edit mode
A to select all
