Headache post CESI

I had an Interlaminar cervical steroid injection at t1c7 aiming left to spread to c5c6 a week ago. I've had one before and my Dr uses all the "correct" protocol.

Since this injection I've been experiencing mild come and go headaches every day with a feeling like my eyes are "strained" and achy along with fatigue. I also have certainly flared up muscle/pain wise from the Injection. I've had sharp pain in my ear just a couple times, which I've never had before. I went to the eye doctor and everything is fine on that end.

I don't feel like the headaches resolve with laying down, in fact laying on my back on the injection site feels the same as upright . Laying on my side does feel a bit better. Sleeping helps and I think caffeine is helping a bit too. I'm able to take a walk and drive. No nausea.

My Dr. seems unconcerned and is dismissive. Maybe he's right but has anyone else experienced this or can advise me what questions to ask regarding a possible leak? My headaches are not severe or like any of the horror stories I've read (I'm so sorry for what so many of you have gone through.) Still, I feel like something isn't quite right and want to be diligent and advocate for myself if this is a possibility. Thank you
