<s>[INST] My sister has some lumpy areas up around the back of neck...she says she is experiencing some burning, she also says it is painful to sit too long in a hard backed chair....she was wondering if she should be concerned because it is a weekend, however she does have an appointment on Monday [/INST] Hi, It can be a hematoma or an enlarged lymph node. As of now, you can take analgesics like acetaminophen or diclofenac for pain relief. If symptoms persist, you can consult a physician and get evaluated. Hope I have answered your query. Let me know if I can assist you further. </s>
