Yesterday I went to NRL in baneshwor for a blood test. After taking the blood the area of needle insertion in my arm just swelled up and I asked her if this was normal. She said it happend because I was holding the cotton swap incorrectly and had to put more pressure on the wound for it to stop swelling. It did work but today I saw this.
So I had given blood samples many time before and this had never happened to me. I was wondering if this will go away on its own or I have to use something on it?
