<s>[INST] Ive had an allergic reaction to the dissolving stitches the surgeon used on my foot surgury 6th dec 2010.  Why when I went back to see and he told me this did he decided to wait another six weeks until the end of feb before removing the troublesome stitch.  Im still in pain and my foot has swollen again. [/INST] Hello, Im Chat Doctor. Looks like it has been some time from your surgery. If It was an allergic reaction it should have not been never better, but being always worse. Swollen foot can have various causes. You will need to see again a doctor, so by asking more information to you, and examining the foot, he will determine what is the cause of your swollen foot. Feel free to ask if you have more questions. Take care. </s>
