Trochanteric bursitis can get steroid injections for it.

The MP diagram is figure 2B. That is where I put 1/2 Lidoderm patch for 2 weeks. I also discovered that HEAT -- in any form will stimulate this nerve.

Notice the lumbar area that gives rise to this nerve as well as sciatica. If you had an epidural to numb your last surgeries, they could have hit BOTH nerves and that is why your pain is mixed. The lateral cutaneous femoral nerve does not go to the back of the leg or below the knee. So you may have a mixed situation. If after 2 weeks your Lidoderm does not work, try placing it across the lumbar area (you may need a whole patch placed vertically in this case).

Doctors are notorious for protecting each other. They will not often admit physician error causing damage (Iatrogenic damage) to patients. So expect this type of evasion from them.
