They can include

Dry or sore throat
Coughing (both a causal factor and a symptom of laryngitis)
Frequent throat clearing
Increased saliva production
Dysphagia (difficulty swallowing)
Sensation of swelling in the area of the larynx (discomfort in the front of the neck)
Globus pharyngeus (feeling like there is a lump in the throat)
Cold or flu-like symptoms (which, like a cough, may also be a causal factor for laryngitis)
Swollen lymph nodes in the throat, chest, or face
Fever
General muscle pain (myalgia)
Shortness of breath, predominantly in children

Voice quality
Aside from a hoarse-sounding voice, changes to pitch and volume may occur with laryngitis. Speakers may experience a lower or higher pitch than normal, depending on whether their vocal folds are swollen or stiff. They may also have breathier voices, as more air flows through the space between the vocal folds (the glottis), quieter volume and a reduced range. Causes
Laryngitis can be infectious as well as noninfectious in origin. The resulting inflammation of the vocal folds results in a distortion of the sound produced there. It normally develops in response to either an infection, trauma to the vocal folds, or allergies. Chronic laryngitis may also be caused by more severe problems, such as nerve damage, sores, polyps, or hard and thick lumps (nodules) on the vocal cords. [4]

Acute
Viral
Most acute cases of laryngitis are caused by viral infections, the most common of which tend to be rhinovirus, influenza virus, parainfluenza virus, adenovirus, coronavirus, and RSV. In patients who have a compromised immune system, other viruses such as herpes, HIV may also be potential causes.
Bacterial
This is another major cause of acute laryngitis, and may develop in conjunction with or due to a viral infection. Common bacterial strains are group A streptococcus, Streptococcus pneumoniae, C. diphtheriae, M. catarrhalis, Haemophilus influenzae, Bordetella pertussis, Bacillus anthracis, and M. tuberculosis. In developing countries, more unusual bacterial causes may occur, such as mycobacterial and syphilitic, though these may occur in developed nations as well. Fungal
Laryngitis caused by fungal infection is common but not frequently diagnosed according to a review by BMJ and can account for up to 10% of acute laryngitis cases. Patients with both functioning and impaired immune systems can develop fungal laryngitis, which may develop as a result of recent antibiotic or inhaled corticosteroids use. Certain strains of fungi that may cause laryngitis include; Histoplasma, Blastomyces, Candida (especially in immunocompromised persons), and Cryptococcus and Coccidioides. Trauma
Often due to excessive use of the vocal folds such as excessive yelling, screaming, or singing. Though this often results in damage to the outer layers of the vocal folds, the subsequent healing may lead to changes in the physiology of the folds. Another potential cause of inflammation may be overuse of the vocal cords. [5] [6] [7] [8] [9] Laryngeal trauma, including iatrogenic (caused by endotracheal intubation), can also result in inflammation of the vocal cords. Chronic
Allergies
Findings are unclear as to whether asthma may cause symptoms commonly associated with laryngitis. Some researchers have posited that allergic causes of laryngitis are often misdiagnosed as being the result of acid reflux.
