The main cure for fractured ribs is time and rest. It would probably also be a good idea to make sure you are consuming a healthy diet with lots of omega 3's and that you consider Bromelain to speed healing. Other items that may help heal the bone and cartilage include hiyaluronic acid, silica, colloidal silver, proteolytic enzymes, tryptophan, glucosamine, chondroitin, MSM, and collagen. If it were me I would make sure to get some Dr. Christopher's Complete Bone and Tissue capsules and perhaps the ointment version too.
Most of those items can be obtained at Utopia Silver Supplements and you can use the CureZone discount code of LR001 to get 15% off any item not currently on sale.
All the best

Why is the Dr. Christopher's a "no go" for you? Many supplement companies ship to Europe.
