Lower back problem with Haemorrphoids.

Hi I was suffering from back problem as well as some sort of numbness in hands/legs then went for physiotherapic exercises after started burning sensation started around waist and below alongwith pain in tail bone.Later started feeling pricking pain in the lower part and now suffering from pricking ,burning sensation and itching from starting from waist lower down (meanwhile suffered from piles in between and took lots of medicines as well) - so i was advised MRI lumbar spine the finding revealed L4-5 mild posterior bulge and L5-S1 posterio-central disc protrusion causing no obvious nueral compromise. Can you pls suggest as to what is the existing issue and whom do I need to consult is it because of hemorrhoids or something spine related issue that I facing these problems ?
