It has been suggested that I have SI joint injection. The pain I have is mostly at night in this area (although sitting in a straight chair for a long period tends to make that area of back ache. The pain wakes me and cannot lie on either side now. Have both hips replaced due to high dose steroid induced AVN and as a result have concerns w/ steroids being injected in my body or orally. One hip is particularly bad with a feeling of fibrous tissue “rolling” across the joint at times during the day and told there is bursitis. Walking is not particularly painful, but can only walk or stand for limited amounts…but rising up and down from a chair can send shooting pains to my hip. Doc feels could be related to the SI joint being inflamed and has suggested injections. Not sure if this is chicken and egg situation with whether the hip issue/bursitis caused the SI joint or vice veresa..but the side hip issue came first. Would like to know more about the SI injection and how often it actually yields good results
