I have been down with gnawing lower back pain and sciatica on the lower side of my legs. My doctor ordered MRI 2 weeks back. The results showed swollen and inflamed L4-L5, which were rubbing against each other, pressing on my nerves and causing the pain. The treatment suggested is an ESI to cure sciatica and facet joint injections to lessen the lower back pain. But it’s taking a very long time to get an appointment to administer these shots. Meanwhile, my surgeon’s PA was kind enough to give me a Medrol pack. She said it might help and yes it actually has. I have been on that medication for 5 days and my sciatica has completely disappeared. I do not have pain but I do feel some weird sensations. It is hard to explain. Is there anyone out here who has used the Medrol pack and found it useful? I want to know for how long the medicine is capable of giving relief? I hope it lasts for long!!!
