There are two reasons for a lump in this area, one is an enlarged lymph node and the other is a localized sebaceous cyst. If the lymph nodes are localized and enlarged, they are usually caused by inflammation of the cheeks or upper respiratory tract. Common acute pharyngitis, acute tonsillitis, or otitis media involve enlarged nearby lymph nodes, which are usually eliminated by controlling the inflammation, usually with the application of antibiotics. Clindamycin, roxithromycin, amoxicillin or cephalosporin antibiotics are commonly used and are more effective. In addition, you can also apply the Chinese medicine or proprietary Chinese medicine that clears heat and removes toxins, relieves sore throat and relieves pain, such as Pu Di Lan Oral Liquid and Blue Scutellaria Oral Liquid. Another cause is localized sebaceous cysts, which are superficial benign subcutaneous swellings that can be treated without special treatment if they do not cause pain or grow fast enough to affect their appearance. However, if inflammation occurs or it grows faster, it must be surgically removed to completely solve the problem.
