[|Human|] I have a large bump on the back of my head, my family doctor thinks it just a swollen lymph node, although it is very painful, espically after I have smoke pot, although I when I put to and to together i stoped, while normally if i hadnt smoked in a fewdays or a week, it would bairly hurt, and the swelling would almost be gone but now it feels swollen more than ever and hurts very badly with a shotting pain down my back raiding from the lymph node, and I have a headach that hurts very badly sitting right behind my forhead.
[|AI|]  Hi. There are no lymph nodes in the situation/ area you explained. This is either a lipoma or a sebaceous cyst. It is better to get this removed (excised) for 2 reasons.1> your get rid of the disease and 2> you get the histopathological diagnosis-makes you tension-free and symptoms free. It is possible that the nerves supplying the upper and lower area are going through the nearby area, so you are getting a typical referred pain.
