I have a patient, 55 year old female with severe SI joint pain on the left side. No specific trauma except perhaps being bumped on the thigh by a large dog running by. This has been going on for 6 months and steadily gotten worse. Plain films, MRIs show moderate arthritis of the facets and SI joints, hips clear, right side is just is bad on x ray but no pain there. Moving from sitting to standing is excruciating, as is getting out of bed. She is ordinarily athletic, no interest in disability and this has totally devestated her quality of life and she is desperate for relief. "Sucking it up" is not an option, this is a US Army veteran who can take a needle without a flinch. Physical therapy, chiropractic, every topical agent, stretching, lyrica, has been tried. NSAID are contraindicated due to a GI bleed. SI joint injections, facet injections, radiofrequency at L4 L5 S1 S2 S3 has not helped. The pain is in the buttock and lateral thigh, severe gripping vise like with a severe stabbing pain when motion is attempted. PRP is planned next. Small doses of opoids do work, no addiction history but she does not like the feeling that she gets from narcotics, does not like the "high" feeling and is asking about a pump her reasoning being that this should deliver pain relief without making her feel like she is drugged. She has also asked about a SCS but this does not appear to be radicular. She will do anything to be relieved of this and is and is willing to pay cash if the insurance company will not cover the treatment. She is really desperate. Any suggestions?
