<s>[INST] I have an infection in my foot that has been diagnosed as cellulitis. I actually have a hole in my foot that will probably need skin graphs. I ve been given iv antibiotics as well as oral antibiotics. I also have one on my arm that has actually burst and is draining right now. In addition to that, there is a redness around this boil like wound that is hot and seems to be moving up my arm. I was told at the hospital that I could get more of these until the infection gets out of my body. I am currently soaking my foot in an antiseptic solution, putting antibiotic ointment on both wounds, covering with gauze pads. I am suppose to go to a wound clinic for followup care. Do I need to go to the er with this redness going up my arm? [/INST] Hello,Welcome to HCM,In case of cellulitis infection spread to the subcutaneous (under skin) tissues as well. I think instead of debating on what caused the boil or bite and made way for the entry of the bacteria it is important to treat fast. I would suggest you to take some lab investigations like CBC, blood culture, routine urine examination and culture of the wound discharge. I suggest you to take oral antibiotics first for at least 2 to 3 weeks to contain the spread of cellulitis. You need anti inflammatory like Ibuprofen up to 600mg per dose two to three doses a day. If the symptoms are still persisting, you may have to make an appointment with your surgeon.Thank you. </s>
