Does complex regional pain syndrome (CRPS) qualify in Illinois?
Yes. The Illinois Medical Cannabis Patient Program (Compassionate Use of Medical Cannabis Program) lists Causalgia as a qualifying condition. An Illinois-licensed provider still has to evaluate you and agree that cannabis is appropriate.
About complex regional pain syndrome (CRPS)
Limited evidence. CRPS falls under neuropathic pain, where trials show modest benefit, though CRPS-specific studies are few.
Symptoms Illinois patients most often hope to ease:
- Burning or stabbing pain in an arm, hand, leg or foot
- Pain from light touch, clothing or bedsheets
- Swelling and stiffness in the affected limb
- Muscle spasms and tremor
- Poor sleep because of constant pain
