<s>[INST] I have had two years of recurring strep infections in my right foot. Now i have had surgery to remove the sesimoid bone because a callous there was opening and that's where the infection was..The doctor felt that would do it. Now five weeks later, i appear to have an infection again. I've had mri's and ultrasounds. Nothing shows up. I also have pins and needles in my feet because of fibromyalgia which i know slows circulation. I'm worried that no one will be able to find the answer [/INST] Thanks for posting your query to Health care magic .If you are having repeated infection you should undergo culture and sensitivity testing for you wound discharge .It would give you  sensitive antibiotic effective for your organism .then you communicate me to know for selection of correct antibiotic .Second thing is duration of antibiotic is again important because if you didnt take antibiotic for a definite duration it will not kill microorganism completely and infection recur . Hope I have answered your question. If you would like some more information I will be happy to provide. You can also write a review for me. Wish you good health Take care! Wish you best of Health.
