Hello , I understand your concern. I am Dr. Arun Tank, infectious disease specialist, answering your concern. MRSA can transfer by sharing of common things, like bed sheets, towels etc. Yes it can transfer to you also. But MRSA wont cause symptoms as you mentioned. It may cause boils, cellulitis, furuncle etc. but it never cause joint pain. You can screen yourself for the MRSA. If you found yourself positive you can clear yourself with mupirocin ointment. Glad to answer your further concern contact me on bit.ly/DrArun We wish you a best health at healthcare magic. Thank you, Dr. Arun Tank If you are satisfied with my answer rate me as five star and close the answer
