Has anyone found out anything further. My husband had the injections done at the end of December 2023. He experienced pain and discomfort in his thigh for the two weeks prior to surgery. No bruising, just pain and discomrot. Now, 4 weeks post surgery the pain is unbearable above the knee in the same thigh area. Like Kathi65 above, it also feels as if his skin is being cut with razor blades from even the slightest touch. He is only able to sleep for a couple of hours a night due to this. It is simply miserable. Any information you have to share would be appreciated.
