Brief Summary:
Demonstrate the ability of subjects suffering from sinus pain to self-treat with the SYNUS Pain Relief device and to obtain pain relief compared to a sham/placebo device.

Condition or disease Intervention/treatment
Sinus; Inflammation Device: SYNUS Pain Relief device

Detailed Description:
A prospective study of at least 58 recruited subjects suffering from sinus pain. At least 30 of the subjects will be randomly selected to use the SYNUS Pain Relief device, a device that uses micro-currents to stimulate major nerve fibers passing from the sinus passages through various foramina to the facial skin. Subjects will read manufacturer's provided Instructions-For-Use (IFU's) and without help from staff will proceed to self-perform the treatment. The other subjects will follow the same procedure but use a sham/placebo device with no stimulating current. Subjects will be blinded as to the device they use. Prior to and 10 minutes following the stimulation, subjects will score their pain level on a visual analogue scale.

Group/Cohort Intervention/treatment
Active device users
Users will use an active SYNUS Pain Relief device
Device: SYNUS Pain Relief device
SYNUS Pain Relief is a handheld micro-current TENS device used for the temporary relief of sinus pain.

Sham device users
Users will use a sham SYNUS Pain Relief device that is not providing treatment

Primary Outcome Measures :
  1. Pain reduction [ Time Frame: 10 minutes ]
    Average decrease in pain score of the SYNUS device is greater than the average decrease is pain score for the sham/placebo device.
