Your symptoms, such as sore throat, cough, tonsillitis, mild fever around 100 degrees F, and body aches, most commonly point toward a viral throat infection, which often spreads through cough, cold weather exposure, or contact with someone already infected. In some cases, bacteria can also infect the tonsils, especially if throat pain is severe or there are white patches, but many infections start off viral and improve within a few days as the body fights it naturally. Because the throat is inflamed, swallowing may feel painful, and body aches may happen as part of the immune response. Right now, focus on rest, warm fluids, and simple saltwater gargles to soothe the throat. Steam inhalation can help reduce congestion and ease coughing. Eating light, soft foods and staying well hydrated supports faster recovery. Avoid cold drinks, smoking, and spicy foods as they can irritate the throat further. If fever increases, swallowing becomes very painful, breathing feels difficult, or symptoms last more than a few days without improvement, a medical check is important to rule out bacterial tonsillitis and decide if specific treatment is needed.
