Is it okay to have 5 or more epidural lumbar spinal steroid injections in one procedure?

No three in a year: Three a year is a common cut off. Concerned about increased infx risk 1 % per injection complication rate now is 5% results don't change after the third many surgeries have a lower complication rate than your cumultive rate.

No: Three a year is outdated. In the past, docs used to do a series of 3 esi's in sequence. Patients were limited to 3-4 "series of 3" per year. This is different from your question, which is how many injections should be part of one procedure. I typically do one or two injections at each sitting, which covers the targeted area. In the past 10 years, I have 3 in one sitting twice. 5 is excessive.
