Loss of movement? Botox for palmar hyperhidrosis.

Thank you for sharing your question. Botox works well for exesssive sweating. It can cause temporary weakness of the hands which often is felt to be asymmetric. This will likely resolve. Inform your doctor if it does not improve or worsens.  Good luck,

If botox caused weakness of hands it could be from botox being injected too deep.  The side effects for sweaty palms and hands are as follows:
Temporary weakness- this is quite rare and to date none of my patients have experienced this.  since botox is a neuromodulator it can impair muscle movement.  Patients who rely on their hands for a living should be cautious and weigh the risks with the benefits.
Bruising and swelling- Bruising and swelling is the most common side effect.  Patients should consider ceasing blood thinners.

Hyperhidrosis of the hands is a common and frustrating problem.  
Botox injection have a great impact on reducing sweating of the palms.  However, if injected too deeply it can affect the intrinsic muscles of the hand.  Thankfully, this should not progress and should gradually improve over the next few weeks. 
Do let your injector know about your reaction to prevent this from happening again in the future. 
Best of luck,
