67 year old male. Slipped, fell down, slammed back against large machinery. 6 days ago. No broken bones, or kidney damage. Injury is on the right side, and when spasm hits, pain shoots almost all of the right side. Received muscle relaxer and pain pills, and ledocaine patches. No pain when I sit, but severe pain (with queasiness) when standing up, picking up stuff, bending. Pain pills help, but patch is useless and so is muscle relaxer. Pain and spasms reduce when I press againt the injury point (a bruise with slight decoloration) when I feel the spasm starting. ER doc gave no info on what to do if pain and spasms occur after meds run out (5 to 20 days) depending on if severity says the same. Advil and Aleve seem best for long term. Thank you.
