Help Please..... After all the success and good reports I've had about my recovery, I am now very scared that I am having a delayed allergic reaction to the metal in my knee. After 6 weeks, everything was going great, and then BOOM, I develop a skin reaction and retain swelling in the upper portion of my knee, right above my knee cap and on my thigh. The rash is very small bumps, but also resembles hives, especially in the morning. It's only on my new knee leg and nowhere else on my body. It is on my calf, around my knee and half way up my thigh, and is very itchy when I'm not taking benadryl. My leg is moving great, with minimal swelling, except for where the rash is. I called my OS Friday, and he said to use Cortizone cream and take Benadryl, and if it's still there on this coming Tuesday, to call the office. So I go out and get what I need, and it helps, but I can't help but worry that it's only helping the symptoms of something that might be brewing inside me that won't go away on it's own. I started to research rash and hives after KR, and all this stuff came up about skin reactions after KR, and people being allergic to the metals used for KR. I am calling my OS tomorrow, not Tuesday because this is scaring me to death. The rash is still there, and I would like some answers. Has anyone had or known of anyone who had this kind of reaction to the metal? If so, can you PLEASE send me some feedback? The last thing I want is an infection, or the need for a revision due to an allergy. Just when I thought I was doing so well!:( WHY????!!!
