<s>[INST] Hello! I was wondering if I could be allergic to the metal I have in my foot and ankle from a reconstructive foot and ankle surgery? I was diagnosed 8 years ago, after my surgery, with RSD, and now MS. But, I have always had an allergic reaction to metals. My surgeons told me the hospital grade surgical steel would not be an issue, as nobody can be allergic to it, but I have seen and read differently. I am curious what steps I must take in order to find out if I am allergic to the hardware or not? I assume a blood test? Thank you for taking the time to read this! [/INST] Hello, Welcome to Chat Doctor, As you are asking a test to know whether you're allergic to metal leading to contact dermatitis there are few tests which can detect this. You may undergo Skin Patch test for a particular metal and find out whether you are allergic to that metal. This test requires 3 days to read the result. The patch will be put on to your back having suspected metal allergen and reading is observed after 3 days. Hope you find some solution. Thank you. </s>
