Saw the consultant for the elderly yesterday. Told me my advanced osteoporosis is reason for back pain etc. After 2 operations on fractured femurs (both l and r) now have. a Spinal fracture . treatment self administered injections over several months. May cause nausea and dizziness. Has anyone any experience of these ?. Now I hear that strontium (previously a remedy for this) has been discontinued as had alendronic acid tabs which caused me all this trouble. Makes you wonder what they will "discontinue" next.
