I fractured my shin two years ago, and it healed. Two months ago I bruised it from impact, it swelled up badly, then healed. Two weeks after, I again hurt it from impact, and was struggling to walk, after that had healed, I have been suffering from throbbing of the same place in my shin, and have no suffered impact to the same place, and it has swollen again. Is it likely to be just bruising or more? What should I do, should I go to hospital?
