One thing is sure from your history. You seem to be having an obvious lump in your back. It may be a lipoma
, sebaceous cyst
or any other swelling as well.
The management is easy. Just get a biopsy
of it and look for the histopathological report. It will confirm the nature of the tissue in the swelling. Excision can be done on an elective basis later on.
I do not think the chiropractor can help you on this.
Hope this helps you.
Get it out of your body soon.
