Can you please elaborate your symptoms. It is difficult to help you out with this minimal details.
thank you for replying its a hard lump just down the side of my ear ive no pain but my ear feels blocked sometimes and whistles regards sabrina196
If the swelling is inside the canal it can be exostosis causing blockage of the canal. If it is below or behind the pinna, it will be an inflammatory lymph node which is commonly noticed in case of minor infections.
Better you can get an FNAC (Fine Needle Aspiration Cytology) done to know what exactly is that lesion.
thankyou for reply i will go to doctors to have it checked and lrt you no thanks again regards sabrina196
