If i continue doing active and passive pt and get a lumbar sympathetic block when i'm home from school. should i have a good chance of beating crps?

Not just blocks: It's not about a single block -- it's your diet, ongoing physical therapy, topical medications, some oral medications... And, yes, blocks as well -- could be one, or could be ten or more.

Moderate; alternativ: I'm not a fan of sympathetic blocks or PT for CRPS.Newer, controversial idea is that CRPS is due to inflammaction of peripheral nerves. 1 approach would be to try applying Vit. D cream to the skin, if you can touch it, or Prologel.Vit B complex (esp. B12) orally.If you get some response, you may be able to eventually tolerate neuroprolotherapy which can calm the nerves & stop the pain.
