Just go ahead and review the brief excellent post – link above. Dr. Fox states in the post that symptoms can include symmetrical bilateral calf pain, a tip-toe gate, or refusal to walk [and in the post, Dr. Fox includes the differential diagnosis of refusal to walk].
In the above post, Dr. Fox reminds us to consider Rhabdomyolysis [go now and review his post on this subject, also].
What follows is from Dr. Fox’s Rhabdomyolysis post [But still, Go Review The Complete Post]:
- Urine dip with +heme but no or few RBCs is concerning for it.
- Myoglobinuria does not have to be present for the diagnosis however.
- Myoglobin is eliminated more rapidly than Creatine Kinase (CK).
- CK levels > 1,000 U/L is often considered diagnostic.
- Lower levels of CK are termed myositis.
