What aside from physical injury could explain pain in the upper/posterior part of the leg (thigh bone), which the patient feels more pronounced on the right side, but which exists also on the left side at the homologue location? The pain radiates slightly into the rest of the thigh bone.
Ultrasound revealed some tissue damage at the right-hand site, possibly hematoma that is a sequela of an old injury (2 years ago) on the right side, or stone/calcifiation. There was no injury to the left side. No orthopedic or other comorbidities.
Are there inflammation markers that can be examined in a blood test that would rule out some of the more plausible internal causes of this symptomatology, such as symmetrical (possibly rheumatoid) arthritis?
