After my right TKR in 2014, my OS prescribed a regime of injections that my husband had to give me in my belly for 30 days after the surgery. I received these in the hospital as well. For the life of me, I can't remember why I had to have these. (Both my husband and I freaked out everytime I had to get one--I am needle phobic!) These were NOT gel shots. Has anyone else had to do this? If so, why are they done? I am going to call my OS to see if he plans on having me do this as well. (Hoping not)! Thanks in advance.
