I am 25 years old and I have received 2 of the 3 shots.I do not remember when exactly I got the first one but I received my 2nd one in June.The first time my arm was sore for awhile and i remember feeling a little dizzy after the injection but nothing to be worried about my doctors made sure I was ok to drive.I got the second one and had no immediate problems.Now when i received my first one my arm had swelled up but it went away after a few days. After the second one I noticed that my arm stayed swollen a little longer well it has been 6 months since I got my second gardasil shot and I still have a lump in my arm. I was told to do some physical theorpy with a doctor or put a heating pad on it and massage for the next two to three weeks and see if it goes away. My doctor said it shouldn't be this way for this long.i know this is not as severe side effect as some of the other people but I thought I should share it.I did not receive the third shot and i don't think im going to.My doctor told one of the nurses to report it to the company. I would advise anyone who decides to get the gardasil shot to do some research first.
