Our Princess needs help

My beautiful sister, Karen Coughlin, and her family are going thru a medical nightmare. She is currently at Shands in Gainesville, FL and the doctors are considering a location where her left leg may need to be amputated after complications from a surgery to remove a rare tumor in her vein. The surgery was performed by a chosen expert in this field in mid-February and after being released to go home, she became very ill and called 911 and was ambulated to a local hospital in Jacksonville. She then was immediately transported by ambulance back to Shands Hospital in Gainesville. Every minute of every day has been daunting. She has gone thru 5 surgeries already to relieve pressure on her leg and there will be more to come. Karen and her husband Chris own and manage their own business that they operate from home. They have only basic health insurance and now they are both not working. It has been 3 weeks and it surely will be many MANY more weeks ahead  before they can tend to their work and income.  Karen has undying faith in God and Jesus and she is at peace knowing He is with her on this journey but the medical costs and other expenses are a huge burden I hope can be lessened so they can concentrate on her health and recovery.  She faces a long road ahead and I hope you will consider giving the support, prayers and love this family needs at this time. 
I thank you so much.
