Sensation for pulse 1 |
The investigator will ask the participant to rate the sensation of electrical stimulation with pulse 1 for the three different conditions. The conditions are: control (not active cream), antihistamine cream, and local anesthetic cream. The scale is 0-10 for the three sensations touch, itch, and pain. Zero means no sensation, and ten is the worst pain/touch/itch imaginable. |
