Interventional study to use erector spinae plane block (ESPB) on diagnoses of posterior or lateral rib fractures, vertebral fractures, pancreatitis, pancreatic cancer, renal colic, and back pain for multimodal pain therapy to determine its assistance with pain relief as well as the patient's use of opiates after block completion

Patients with the listed diagnoses will be offered and then consented for an ESPB under ultrasound guidance. They will rate their pain before and 30 minutes after the procedure using the ordinal categorical data on a numeric pain scale. Total patient opiate use will be gathered up to 8 hours after block completion.

Inclusion Criteria:

• Posterior/lateral rib or vertebral fractures

• Renal colic
• Back pain

Exclusion Criteria:

• Unstable vitals
