Bacitracin/polymyxin B (trade name Polysporin among others) is a topical antibiotic cream or ointment. The active ingredients are polymyxin B, bacitracin and occasionally garamycin or gramicidin. Though Polysporin is marketed in the United States, it holds a much smaller market share than in Canada and acts as a substitute to J&Js Neosporin for those allergic to the antibiotic neomycin; although allergy to Bacitracin/Polymyxin B has also been reported. There is also an ophthalmological ointment, eye and ear drops. References

Cause
The lateral femoral cutaneous nerve most often becomes injured by entrapment or compression where it passes between the upper front hip bone (ilium) and the inguinal ligament near the attachment at the anterior superior iliac spine (the upper point of the hip bone). Less commonly, the nerve may be entrapped by other anatomical or abnormal structures, or damaged by diabetic or other neuropathy or trauma such as from seat belt injury in an accident.The nerve may become painful over a period of time as weight gain makes underwear, belting or the waistband of pants gradually exert higher levels of pressure. Pain may be acute and radiate into the rib cage, and into the groin, thigh, and knee. Alternately, weight loss or aging may remove protective fat layers under the skin, so the nerve can compress against underwear, outer clothing, and—most commonly— by belting. Long periods of standing or leg exercise that increases tension on the inguinal ligament may also cause pressure.The lateral cutaneous nerve of the thigh can occasionally be damaged during laparoscopic hernia repair, or scarring from the operation can lead to meralgia paraesthetica. Diagnosis
Diagnosis is largely based on patient  description and relevant details about recent surgeries, hip injuries, or repetitive activities that could irritate the nerve.
