HI Thank for choosing HCM, Antibiotic in case of running nose?? seems so weird, just second generation antihistamine would work nicely, no need for antibiotic, x-ray report you stated here that accumulation of fluid in the head there must be some misunderstanding, you must have been wrongly understood it, questions comes out, where in the head, plain xray difficult to judge the fluid image, have discus it, mean while give her steam inhalation, ask her to drink plenty of water, try second generation antihistamine ( Loratidine ) would give good result, it seems sinusitis, ( Frontal ) Combination of Acetaminophen and Ibuprofen would help her a lot for pain, try it Good day.
