I thought my knee was going to have to be drained but....it feels great now and hardly any swelling or pain
really works!  I slammed the fence post driver on my knee back in May and the swelling was up and down for a few months.  Then I rented an excavator to do some projects and the hopping on and off that and the tractor made my knee swell double what it had before and I wasn't getting any relief from elevating, ice/heat packing and I even tried wrapping it in sodium carbonate all night while elevated.  The first night I took this BulkSupplements Pure Glucosamine Sulfate, the next morning I couldn't believe how good my knee felt.  The tightness behind my knee was gone and I could smoothly walk down the stairs without cringing every time my knee bent.  I'm walking normal now (only Tues. morning and started Saturday eve).  I still have some odd feeling on the inside lower part of the knee (which I am getting it checked next week) but again, I've only been taking it for a few days.  Amazing stuff.
