I’m not sure about your particular situation but find for myself any time I have injections my pain increase for at least a week. Day of and after is always the worst for me. Have to schedule to not do anything. With steroid injections I always get increase of pain for at least a few weeks (not worth it and no relief). I just had a diagnostic analgesic injection last week and feel like my back muscles have been tighter since getting it and increasing the pain & pressure surrounding even tho the analgesic somewhat worked. I took a diazepam before the injection and still uncontrollably flinching even when my doctor just touched my back. He said should have taken 2 of the muscle relaxers so I’m thinking I’m just really tight and my body wasn’t happy with it. Assuming if I could get my muscles to relax it would’ve been better relief. My doctors have told me my reaction to injections are on the uncommon side though.

I get this with my injections, both steroid and the nerve ablation. I have had about 8 steroid injections, 4 test injections, and 1 ablation. I am having another ablation later this month. My doctor offers sedation and I take it every time unless I am getting trigger point injections. The pain the day after is always intense. I hate it but it also tells me that we are working on the right spot. I am so afraid of making my back worse so in a way it is reassuring to know we definately are on the right track.
