I had mine on Monday and I was wondering whether it was normal that my arm still hurts and that there is a swelling where the needle went in, I knew it would hurt but wasnt expecting it to be a 48 thing (or more if it carries on!
The vaccine that you will have received does not just contain whooping cough, it also contains low dose tetanus, diptheria and polio (in Scotland the vaccine is called Repevax and it is the same injection as baby will get as their first injection). The tetanus part of the vaccine will tend to give you a lump at the injection site and then the achey feelings that you have been having! If you have been unlucky enough to get the symptoms they tend to go away after about 5-7 days!
Your midwife/practice nurse/doctor should have explained the side effects to you before they gave you it!
I asked to have mine in my backside, which is supposedly less effective but I did forget all about it and wondered why I felt ill a couple of days afterwards! It took two weeks for my arm to stop hurting after my flu jab and couldn't sacrifice any more precious sleep.
