Hi, welcome to our site. I am Dr Saumya Mittal, MD. Read your query. That is a very significant question and i appreciate your problem. I will try my best to answer your query There are a huge number of possibilities. The swelling of a neck needs to be examined to make sure what it is. That of course cannot be done in this case. Suggest to check an ultrasound of the neck to find out what it is. The other alternative is to have it removed with the help of a plastic surgeon. This would be good cosmetically, since I have a feeling that the swelling is playing on your mind. And second, they can do a biopsy of the tissue removed and tell THE EXACT problem. I hope this helps you. Inform the reports mentioned above/if any other so I can be of help further. Best of luck. I have given you the answer to the maximum considering the information provided.
