osteoarthritis
"Well I have had a Synvisc injection in each knee once a week for the past 3 weeks.  Unfortunately, the swelling and stiffness has been almost unbearable.  I have a very high tolerance to pain but it has kept me up at night for the past week.  I am now icing my knees for 20 minutes every 2 hours and staying off of my feet as much as possible.  I have read that these side affects can last up to 3 weeks (I hope not).  It is very difficult to get up off of the toilet and have had to use a cane the last 2 days.  It has now been a month since my first injection and I noticed the symptoms worsened with each one!   They have cost me $700 from Canada.  Insurance would not pay for medication."
