I've not seen anyone mention using HA for Bursitis, but I wanted to post my experience with this product. I was diagnosed with Bursitis in my shoulder about 2 years ago. I didn't want to get in the cycle of taking prescribed meds full of chemicals (and the cost!) so I just suffered through it. The pain got so unbearable that I could almost cry at my desk every day. I heard about HA from a local radio DJ who was bragging about how this helped his joint paint, so I thought, what the heck. It can't hurt. It did more than not hurt, it took away 95% of my pain within 4 days. I will not go without this product. Ever. It's may daily routine to take 100mg a day. I have noticed my hair is much softer, which is a icing on the cake. I love this so much, I stated using the serum (from InstaNatural) and love it too. P/S Jarrow is the only brand that works for me. I tried the less expensive NOW brand and threw the bottle away when my pain came back days later
