This is what I read on the runnersworld website.
Pain on the anterior (outside) part of the lower leg may be compartment syndrome—a swelling of muscles within a closed compartment—which creates pressure. To diagnose this condition, special techniques are used to measure the amount of pressure. Sometimes surgical “decompression” is required. The symptoms of compartment syndrome include leg pain, unusual nerve sensations, and eventually muscle weakness.
I guess people misdiagnosing is fairly common with easy access to google.
Do you think it is shin splints then, which from what I understand is just a general term for pain in the lower leg?
