Hi, dear I have gone through your question. I can understand your concern. You may have some soft tissue tumour or inflammatory swelling. It is not related to your sinusitis. You should go for examination and if needed go for fine needle aspiration cytology. It will give you perfect diagnosis. Then you should take treatment accordingly. Hope I have answered your question, if you have any doubts then contact me at bit.ly/Drsanghvihardik, I will be happy to answer you. Thanks for using health care magic. Wish you a very good health.
