Spinal nerve treatment (epidural and nerve root injection)
Spinal Nerve Block
Severe pain often results when nerves running into the limbs are compressed by disc damage or foraminal stenosis, or by inflammation and swelling.
In such cases Medication is delivered directly to the compressed nerve root or the epidural space under real-time imagingreduces inflammation and swelling and blocks the pathways transmitting harmful pain.
The procedure is brief, requires no anesthesia, and no hospital stay.

Precautions before and after the procedure
1. A small dose of steroid is used only when inflammatory pain is severe. Steroids must be used when genuinely indicated, but repeated high doses carry side effects, so discuss this with your physician.
2. The injection may temporarily paralyze a motor nerve. This generally resolves within a week.
3. When local anesthetic is used in large amounts, some may be absorbed into the bloodstream and cause systemic symptoms immediately after injection, though dangerous reactions are generally not seen.
