Choose your painkillers with care
.... Aspirin is one of the few NSAIDs that appears to kill
pain without this side effect. "Ibuprofen and indomethacin delay bone healing by about one to two weeks in rats, which is the equivalent to slowing it down by 25 to 50 per cent in humans," says O'Connor. None of the rats treated with rofecoxib mana...
