I have cellulitis in my lower right leg. I have been through many test and they can't seem to find out why it wont go away. I went back to my family dr today and instead of giving me loracet plus like I have been on and what didn't make me sick and helped the pain, he gave me ultracet. One of my family members said that I would like them, that they would really help me. Well that goes to show how every medicine effects everone differently. I took my first one at around 1:30pm today, it didn't do anything for the pain, so at about 6:00pm I took another one. Well let me just say that will be the last one I take. It is now 1:30am here and I am not sleepy at all. I have no energy, but I just can't sleep. I keep itching everywhere. My legs, arms, back, face, and my hands. My pain is still present also. I am going to go back to my dr in the morning if I can get in to see him and I am going to go ask him if he has ever taken these before, and if not, for him to get a few and take them and see how they do him. Maybe that will stop them from being perscribed. I would not recommend them to anyone. I know everyones body reacts diferent, but why take the chance on having these symptoms and many more.
