If numbness happens every night or lasts longer than a few minutes.
If you also experience weakness, pain, or loss of grip strength.
If numbness occurs during the day as well as at night.
If you have neck pain, back pain, or shooting sensations along with numbness.
A doctor (usually a neurologist or orthopedic specialist) may recommend tests like a nerve conduction study, EMG, or imaging (like an MRI) to find the cause.
✅ In most cases, nighttime arm/hand numbness is due to temporary nerve or blood vessel compression from sleep position. But if it’s persistent, worsening, or affecting daily life, it’s best to get checked.
