Im 64 woman with oa of both knees. I have had about 3synvisc one shots over the past 3 years. With no problems.Yesterday I had both knees injected with synvisc one. Right knee is perfect. Left knee very sore and swollen egg size lump on medial side. Very difficult to bend or bear weight. Dr said he hit a blood vessel at time of injection and I would have a bruise. I have a small bruise at the injection site. The large egg swollen area concerns me that the injection didn t, go into the joint space. I put ice on the knee for 24 hr on and off. I have now switched to heat what should I do.
In my opinion you should continue ice for 2 more days than switch to heat, I think he hit a bursa not a blood vessel, no chance that he injected it out of the joint in my opinion also use anti-inflammatory, I recommend alphinternGood Luck
