Physiotherapist with 1+ years experience
Abby is a 23 year old female with a desk job in corporate finance. She has had a recent increase in time spent working from home (longer weekdays, also working weekends). Abby is Right hand dominant.
Abby has been experiencing Right upper arm pain as well as pain and pins & needles into both hands.
She recalls neck and medial scapular pain on her Right side recently but states that it’s quite common to experience that pain during periods of intense study or work.
Abby’s upper arm pain has been worsening for 3 weeks, extending from the upper triceps region into her forearm.
The upper arm pain interferes with sleeping but there seems to be no obvious AM/PM pattern.
Abby is unsure of any specific aggravating factors.
The pins & needles have been around for 6 weeks but not worsening, mostly occurring at night.
No relieving activities have been identified for the pain or pins & needles.
Abby took paracetemol and ibuprofen for one week – it may have helped with the pins & needles but there was no change to Abby’s arm pain.
After attending her doctor, Abby’s GP ordered an X-ray which was reported as normal without adverse findings.
