..yes I agree with your Dr, and this is basically what mine said as well. He went on to say if it bothers the nerves and or blood vessels, then he would do surgery on it, but again that it could come back. I have left mine alone...and would never Let Dr Sherrine come within 100yrd's of it! I'm afraid she would leave me with more lumps than I have already! ...and I'm already beat up as it is!
(side note: I personally think these are caused from patients throwing their left over med's in the trash and contaminating the Environment!,.... and not down the sink or toilet, where the wastwater can be treated)
Good luck!
