osteoporosis
"On Forteo for 7 weeks now.  Saw a Rheumologist who did a bone density  told me that I was at high risk especially for wrist fracture due to low bone density. Said my spine looked ok. Said I needed Forteo for 2 years the osteoporosis was so bad.  Since starting Forteo I feel extreme fatigue all the time.  Also feel muscle weakness, can't  keep up with my light exercise routine.  Also have had multiple aches and pains in my joints and long bones of arms and legs. Feel deep in the bone, not  muscle.  Pain seems to migrate from one bone or joint to the other since starting 
Forteo.  Redness, and bruising at injection site. Worst symptom fatigue. May have to stop Forteo"
