Lumps at injection sites

Hi, hope someone can help. Been type 1 thirty years now and few years ago told had lumps at injection sites in abdomen so told to avoid tis area. Three years on despite not going anywhere near this area I still have the lumps. I do rotate grately with sites but wondered if anyone had any ideas to rid these lumps. And could these be permanent? Thank you, Chris

It depends… Personally, I would see a dermatologist. Sometimes they have creams that can help with that. It may not go away without the use of cortisone, or something similar.
