Hi and welcome,
I know you've just asked about your spinal MRI which showed a mild disc bulge "c3-c4 mild disc bulge indenting ventral thecal sac uncinate facet hypertrophy" but that would be way too high up your spinal column to be effecting the sciatic nerve, so unless you have additional structural issues and or spinal cord lesions lower down your spine, the problem might actually be with the Piriformis muscle and not coming from a spinal issue at all.
Piriformis syndrome is an uncommon cause of sciatica. The piriformis is a muscle that lies deep underneath the gluteal muscles of the buttocks. The function of the piriformis muscle is to externally rotate and stabilise the hip.
The sciatic nerve passes directly underneath the piriformis. Piriformis syndrome occurs when the piriformis muscle becomes tight, goes into spasm, or swells. When this happens it compresses the sciatic nerve beneath it. In roughly one in 7 people, the sciatic nerve passes through the piriformis instead of underneath it — and these people may be prone to sciatic nerve problems."
"What’s the Treatment for Piriformis Syndrome?
After a thorough assessment of your back, pelvis and hips, your physiotherapist will determine the cause of your pain.
Once your diagnosis is established, treatment could involve any of the following:
*Pelvis and spine re-alignment techniques.
*Joint mobilisation to restore normal joint mobility, the range of motion and function.
*Massage or electrotherapy to help decrease pain and spasm in your piriformis and increase blood flow plus soft tissue extensibility.
*Stretching program for muscle length and flexibility
*Acupuncture or Dry Needling to reduce muscle tightness around the buttock.
*Deep core stability and hip strengthening exercise to stabilise your hip, pelvis and spine.
*Foot orthotics or exercises, if indicated by your physiotherapist or podiatrist, to help restore foot and lower extremity alignment."
I would think because you're a diagnosed MSer and or the coinciding time frame of injecting in to your buttox and when the sciatic type pain started, it's definitely possible for the Piriformis muscle to be the issue....i would suggest you consider seeing your physiotherapist for an assessment and work out the right type treatment plan to help you.
Hope that helps........JJ
