Kindly follow these signs & symptoms such as any associated fever
with such swelling, any history of loss of apetite, loss of body weight, night sweats
, unexplained cough
for a prolong time, etc. Now, if you think you do have two or more such symptoms then you are advised to see a Surgeon/Physician immediately for a clinical review. Your Doctor might ask you to go for a histological/biopsy
test for your prolong swelling. This can rule out almost all possible pathological or neplastic cases. Thanks.
