Does a herniation cause you not to be able to sit at all or lay on your back . burning pain and pain in other parts like hips, groin, sensitive thighs?

Possibly: It does sound like you might be very sensitive and/or that it might be a major tear. Seek advice from your Dr re possible corrective surgery and perhaps a good PT program once the healing can tolerate strengthening. Try to be patient. Try to find cold/heat/support solutions to pain to avoid opioid risks - but some safe pain meds might help.
