The conversation between human and AI assistant.
[|Human|] Yesterday my 61 yr old sister had itching on her scalp on the left side and later in the day a small bump appeared and in this morning she woke up with a terrible headache and there was a large lump on the side of her head. She went to the emergency room at Intermountain Medical Center in Salt lake City, Utah and was told she was having a migraine headache and was given Keflex and sent home with a prescription for more Keflex. The lump has gone down some and her headache is better. So what is the lump from I never heard of a migraine with a lump on the head. They told her it was on the outside of the skull.
[|AI|]  Hi, Thanks for writing in. From the description of the lump on the head, it appears that it might be a scalp swelling, There are many kinds of swelling involving the head and scalp. Some of these remain inactive for a long time and then get infected and become enlarged in size with development of pain. These are commonly cysts like sebaceous cysts and can have a central opening when looked at closely. If doctors at ER have examined your sister then it is certainly not a tumor that is growing from within. As lump has gone down after taking reflex therefore there is an infection that is now under control. Migraine cannot be the result of a lump and cannot cause one. Migraine is a different medical entity and not related to the lump.
