hi I understand your situation I think you get chronic compartment syndrome (exertional compartment syndrome) which is common in athletics due to increased intra compartmental pressure which lead to decreased blood supply to muscle and nerves and causing low oxygen and pain Diagnosis: by measuring intra compartment pressure examination and x-ray to rule out tendinitis and stress fracture Treatment: rest, stopping physical activity and non-steroidal anti inflammatory drugs may help. I hope information s useful.
