<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have a enlarged lymph node on the right side of my neck, I first noticed it about a year ago, I also had one that came up on the back of my head, behind my ear on the right side as well. I went to the doctor and they said it was because of an infectionvirus and that it would go down. up until that point I had been perfectly fine with no infectionsviruses. the one behind my ear did go down but the one in my neck has stayed and got slightly bigger. I went to the doctors again after having the lump for about 6 moths and was told again that it was nothing and it would go down. I then started to get migraines after going on the contraceptive pill, and feeling generally unwelltired, so i stopped taking the pill and went back to the doctors, they did some blood tests as my doctor though it might be glandular fever, but these all came back fine. I still have to lump, it aches from time to time and I still get migraines, usually around my period, which can last for days. recently Ive also been getting painaching in the colar bone region of my neck upwards, especially on my left side, there doesnt seem to be any more lumps though. if that makes sense? should i be worried?  <response>: Good morning Madam, Thank you for sharing your concerns with us. I will try to help you as much as I can through my answer. As I understand, you have got two problems. The first one is a swelling most probably an enlarged lymph node in the neck. If a lymph node stays enlarged for a long time without any signs of infection warmth, redness, pain, it is safe to have it removed so that it can be seen under a microscope to make sure that there is nothing dangerous. I would recommend you to discuss this option with your doctor. The second problem is a headache. Oral contraceptive pills are known to cause a migraine. It can also occur around the time of menstruation. If a migraine is too frequent and is disruptive, then I would recommend discussing the option of prophylactic medicine for this condition with your doctor. I hope this answers your question. Please feel free to contact me if you have any other query. Sincerely,
