Shoudl allergic reaction flair up again after meds are taken?

you could be allergic to the medications that he gave you for some medicines do make you itch and have a rash and etc. I think if i were you i would go back to him and let him know this, If your feeding right now, I think i would stop for now and use formula so that way you will feel a little bit more comfortable with your situation and if they are giving you meds you dont want your baby to get any of the meds in her while you are feeding him or her. If it does not become any better than yes you may need to go to the er so that you can be seen, Make sure to take your medicines that the doctor gave you and not to forget to tell them that you did see your doctor and tell him what was happening, I dont think i would let it last to long, some medicines are not good to play with since it can do more harm than help, I surely do hope that you will get better soon.If you have a friend that you are close to then i would call that person so that she can watch your baby while you are going to the er. And good luck.
