Dentnal Hygiene.
Static posture for hours at a time sitting with my held tilted to the right
holding my elbows up and out for hours to hold the dental mirror and instruments, reaching for the overhead light and Cheap dentist who don't want to invest in their practice to get updated equipment. Unforgiving patients who can't seem to recline in the chair all the way but yet they lay down to go to sleep at night..go figure. I started rescheduling them with someone else if they wouldn't compromise. With the exception of elderly, pregnant, gastric and physicallyinjured or handicapped of course but it took me after the 4th and 5th surgery to figure that out.
