Hello Amanda,
Thanks for the information. The abnormal sensation which is termed as paresthesia seems to be originating from the thoracic spine, around middle of the back. This can be because of the degenerative spine disease, disc disease or spondylosis. The mainstay of the treatment is physical therapy. Meanwhile avoid pushing, pulling, or carrying heavy objects.
The hot sensation is unlikely to come from the visceral organs and is not related to the intra-abdominal structures.
A MRI of the lower thoracic spine would be informative. Specialist to handle this would an orthopedist.
Please feel free for the follow up questions.
