Blood culture symptoms and conditions

My 17 year old son was diagnosed with MRSA after getting an injury on his knee from playing basketball.After the first does he had a loss of appetite, fatigue, nauseous and severe headache. By the third day he got a fever, chills, neck stiffness and a feeling of doom. We went to the ER because his blood had not been cultured and we were afraid of sepsis in the blood. The ER doctor said it was most likely viral and sent him home. The next night he had a fever of 103, sore throat, trouble swallowing, sun burnt look, swollen eyes and cracked swollen lips.The next day we went to the urgent care and they tested him for mono, strep and the flu...(all negative). He felt awful and was so tired and feverish. The next morning he woke up with a severe rash and itching all over his body and his skin looked like it was scalded. His blood culture came back negative for bacteria and his wound has healed. I have taken him off of this drug Bactrim. This is his first day. His rash is better and his fever was down for a little while. It is 101 tonight and he just feel so tired and achy. I know it will take time for this to get out of his system. Meanwhile he is missing school and is getting depressed because he feels like he will never get better. If someone told me that fever and chills were a side effect from this drug I would not have been so worried that he could die of a blood infection. Ask lots of questions or google this site before taking a new drug.

I had been taking bactrim for a week when one morning i woke up feeling achy, tired, and light-headed. I noticed a slight rash forming on my arms but didn't think much of it bc i had been on the Bactrim for a week already. Then the symptoms got wayyyyy worse. I started to form lesion like sores on my vagina, and I immediately saw a doctor to get tested for STD's. The gyno examined the area, and she said it did not look like herpes but that she would test for it just in case. She put me on augmentin bc she said I definitely had some sort of infection down there. After taking 4 doses of augmentin almost all the lesions went away. The STD tests (blood, culture, and urine) all came up negative, as I expected they would. Has anyone else had genital reactions to bactrim???? Because as of right now the doctors are unsure what caused this outbreak/infection.

My 19 month old was hospitalized for 3 days with a high fever and all the symptoms that go with ...ie: body ache, fatigue, loss of appetite, dehydration. this took place after a 10 day amoxicillin course. In the hospital they started Omnicef via iv. after getting home he seemed to slowly get back to himself, with a few issues...waking up with "night terrors" cranky, loud, clingy, loose stools. his fever was down but not gone and his cough and runny nose seemed to be getting better. that is until today. we are 8 days into a 10 day with Omnicef and today his fever has returned (back up to 101 to 102) and his nose is running again. so 2 antibiotics down what next. between, all tests in the hospital came back negative until the blood culture came back and determined a blood infection. I am calling the hospital pediatric doctor in the morning to report on his repeat symptoms
