What is the cause of pain?

Participants reported the following
causes of pain:
-55% low hemoglobin
-40% bone pain
-30% muscle spasm
What is the cause of pain?

Analyzed whether the following were
significantly different between
participants with and without pain:




Hemoglobin level.
Bone Density severity, Fracture history.
Iron overload.
Chelation method.
What is the cause of pain?

None of the factors were significantly
different.

No clear pain cause identified.
How is pain managed?

63% used pain medications



Non steroidal anti-inflammatories-52%
Acetaminophen (Tylenol)-34%
Short-acting opiods-17%
Long-acting opiods-8%
How is pain managed?

47% reported decreased pain with
blood transfusions.

43% reported decreased pain with rest.
Summary of Findings





Pain is common.
Pain frequency and severity increase
with age.
Pain is chronic.
Pain primary site is back.
Pain etiology-elusive.
Case Study I

Ralph is a 49 year old male with Non
transfusion dependent Beta Thal.



Chronic back pain for greater than 10
years.
Poor bone density, no history of fractures.
Hemoglobin averages 10-10.5
Case Study

Evaluation: Initial assessment




pain located- along full length of spine.
severity-7/10.
radiates- intermittently down legs.
numbness/tingling, loss of strength-not reported.
Case Study I

Further evaluation:


