"Today was my third set of injections in both knees since 2015.  I opted for the one shot dosage as opposed to a series of 3 (why would you want to get stabbed 3 times instead of 1???)  Like night and day.  Dr. said he's had patients do this for 10 years to avoid knee surgery.  He also advised that when the shots don't work and it is affecting my quality of life, then it is time for the surgery.  So far this has been a God-send.  First time it lasted 6 months, second time almost a year."
