What is the main cause of long-term pain after a painful lower limb injury?

  Patient: Description of the condition (onset time, main symptoms, hospital, etc.): 10 years of old injuries have not been well developed, new bone injuries are difficult to heal, and slowly pain like old injuries, previously played sandbag `soccer, leaving the injury never pay attention to, did not expect the bones of the lower legs, or bruised bones began to hurt in the past few years, but before not playing sandbag `soccer when the foot root also occasionally pain, until now also did not find the cause. Until now there is no clear reason, there is a suspicion that it is a kidney deficiency, there is also a suspicion that it is not an old injury, after all, it is after playing sandbags `soccer before the special pain up, only slowly began to pay attention to the previous injuries left by those who played sandbags, now most of the pain in the double calf, are a little dark pain, before the foot was also sprained, until now is also like a sprain pain, even if these months there have been two new Even in the past few months, there have been two new collisions, which also hurt the bone, and the new bone pain is the same as the old pain, which cannot heal itself, but the hand and shoulder joints, which have not been injured, are now starting to hurt. I have had blood tests and X-rays of both calves. But no problems were found. I’ve been taking all kinds of medication for several years, but I haven’t seen any improvement. I’ve used various methods to rub the painful bones with various kinds of medicated oils, and some of them have gotten better, but after rubbing them for a while, I don’t rub them as much as I would like to, and the painful places will slowly get darker. What kind of bone problem could this pain be? How can I find out the cause? Have you seen this kind of pain before?  Doctor: Most of the traumatic injuries caused by excessive sports will damage the myofascia and leave adhesions and scars, which will often cause pain by trapping small blood vessels and nerves in the area. The treatment is to loosen the adhesions and improve blood flow so that the nerves are not compressed and stimulated. However, a diagnosis is needed to target the cause.
