Will OHIP cover lipoma removal in Canada?

Ive had a lump just under the base of my skull for 4 yrs since Ive had it Ive been getting severe headaches some so bad my vision goes black. The amount of tylenol Ive taken over the years is definitely not healthy. First I was told its a lymph node now being told its a lipoma I know a removal is cosmetic so it usually won't be covered but this is really affecting my life, might be growing into a nerve is there any chance at all at OHIP coverage? Im on ODSP and cant afford the $600 I was quoted.
