Botox injection for complex regional pain syndrome
Treatments studied
Part of Brain & nervous system clinical trials.
This study tests whether injecting botulinum toxin (Botox) near nerves in the neck can reduce chronic arm or hand pain in people with complex regional pain syndrome (CRPS). It aims to see if this treatment can provide longer-lasting pain relief than a standard nerve block.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be between 19 and 80 years old.
- You have complex regional pain syndrome (CRPS) in one arm or hand.
- Your arm or hand pain is at least 4 on a scale of 0 to 10.
- A previous nerve block test showed your skin temperature rose, which means a block might help.
- You must be on a stable medication routine for at least 4 weeks before the study.
- You cannot have certain other conditions (like serious blood vessel disease, bleeding problems, infection, or cancer) or be pregnant or breastfeeding.

This trial studies whether noninvasive brain stimulation (TMS) can reduce pain in people with complex regional pain syndrome (CRPS). It may help if your CRPS has lasted at least a few months and you can safely undergo the stimulation and study tasks.
This study tests whether a specially targeted injection of botulinum toxin (like Botox) around nerves can help reduce pain from CRPS. It aims to see if the treatment is safe and doable for people with long-lasting CRPS.
This study tests if freezing specific nerves (cryoneurolysis) can reduce pain caused by muscle tightness (spasticity) after a brain or spinal cord injury, or from multiple sclerosis. It is for people who already get Botox injections for this pain.
This study compares two treatments—a Botox injection or a numbing medicine injection—for the burning, stabbing pain from a nerve lump (neuroma) that developed after a combat-related amputation. The goal is to see which treatment provides better pain relief for at least 3 months of pain.
This study compares two injections—a nerve relaxer (botulinum toxin, like Botox) and a numbing medication (local anesthetic)—to see which better eases pain from a neuroma, a painful nerve lump that can form after a limb injury or amputation. If you have this kind of pain, the trial may help find a treatment that works for you.
This study tests whether injecting botulinum toxin (Botox) into the hands or feet can relieve pain and help heal sores caused by Buerger's disease, a condition that narrows blood vessels and reduces blood flow to the fingers and toes.
