Your persistent forehead pain and low-grade fever likely point to sinus congestion (sinusitis). Since you are already taking Paracetamol and a strong antibiotic (Novamox CV), please do not self-medicate with more prescription drugs. To relieve the sinus pressure, you can use a saline nasal spray and continue plain steam inhalation. Ensure you drink plenty of fluids and rest to combat the weakness. Please do not stop your current antibiotic course midway; instead, consult your prescribing doctor. They may safely add a targeted decongestant or antihistamine and re-evaluate your symptoms, as viral sinus infections do not respond to antibiotics.
