Hi, for the last 5 months I have had 3 lumps in my neck, pea size, they do not hurt, but recently my neck aches where they are, I have been to the doctors a few times, my blood test was fine, and was told i had no infections, and to keep an eye on the lumps, I recently found a very small lump under my chin, my body is so tired i just want to lie down all day and do nothing, On a few occasions my right leg goes totally numb and im unable to walk it last a few minutes, I get bad headaches including migraines. My doctor has now put me forward to see a hematologist, in the day if i do anything little, like standing up and washing the dishes i sweat so much,this has been happening for ages now. I am getting very bad lower back pains, and stomach aches the last few weeks, as of yesterday I have felt quite poorly, and last night my neck felt swollen and realised i now have a swollen left tonsil, which is slightly white there is no pain whatsoever. Sorry for going on so long just wanted to put across everything

Hi, dairy have gone through your question. I can understand your concern. You may have some enlarged lymph node in neck.  It can be due to enlarge lymph node.  Lymph node enlargement may be due to reactive hyperplasia, tuberculosis or lymphoma.  You should go for biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
