MRI Scan After Epidural Injection Shows Moderate To Left Neural Foraminal Narrowing. What Does This Mean?
I am Dr.Omer and I went through the details and I shall try to help with your medical puzzle.
You told that you had pain / numbness on the left side of body (arms?) and you underwent cervical epidural injection because of the spur that was pressing against the thecal sac. Now after 6 days of injection you had severe pain of your life - occipital, frontal in location with muscle stiffness of neck and back, with some relief in pain while lying on side , but not lying straightly , aggravated by movement? , walking? , sitting?.
Based on this description, I think the following are your plausible causes:
1. Post traumatic lumbar puncture headache(PTLPH)
2. Low spinal fluid headache
3.Postural tachycardia syndrome(POTs)
PTLPH as the name indicates is due to the cervical injection they gave you. It starts from 4-8 post injection day and continues for 2 week / month or even rarely years; again the pain seems to be maximum while in upright position or any position but can be relieved by lying on one side
Low spinal fluid headache is actually an overlapping disease with PTLPH. Here the pain is felt in occipital / frontal areas. It is more common seen in young females. The headache can start any time even after epidural injection, sweating , fast and slow heart rates
It is not necessary for the patients with PTLPH and low spinal fluid headache patients to have less pain on lying down , some have less pain on standing , and some have less pain when lying on side
Postural Tachycardia syndrome causes the headache on any posture , with variable heart rates , blood pressure , sweating, etc. This is also more common in female and can be triggered by epidural (traumatic ) injection.
Both the MRIreports show almost same reports
PTLPH and low spinal fluid headache are best treated by 2-6 times of epidural patches - one is seldom enough (10-20cc of your blood). Though your leakage is less, most patients are treated with more than 1 epidural patches
Epidural patches are not life threatening in any way , but they do have some complications like muscle stiffness and leg paresthesias.
Other treatments include fibrin glue injection at leakage point ( but less effective than epidural patch)
MRI with gadolium myelogram is the investigation of choice for PTLPH and low spinal fluid headache. it is safe as gadolium is safe. Myelogram was XXXXXXX before the invention of gadolium; so don't be worried.
Your pain doctor is going right , you need caffeine with lots of fluids and get a second epidural patch with a difference of >5 days from first injection
The best plan of action will be to get the MRI/CT myelogram and then go for second epidural patch at the specific leak point with more than 30 ml of your blood. Don’t worry the new leakage point of the needle is completely closed by the blood we give.
I hope this explains your query in detail. Let me know if you need clarifications.
Wishing you a speedy recovery
Take care
