<s>[INST] 17 year old daughter has a lump on the top of her head (left side) about the size of a kidney bean. She has been complaining of headaches the last couple of days. She just told me about the lump tonight. Whenever she touches it (or I touch it) it hurts and she feels nauseous. She suffers from ulcerative colitis. Is t h were any relationship. Trying to get into the doctors tomorrow. [/INST] Hi. Thanks for your query. Noted the history about your 17-year-old daughter having a kidney bean sized lump on the left side of head, headache, hurts on touching and also has ulcerative colitis. Wants to know what is this and any relation to ulcerative colitis. As per the history you have provided, this looks to be an infected sebaceous cyst for which scalp is most known to occur. Hence, not related to ulcerative colitis most probably. You can get her checked by a General Surgeon, get this operated and if fixed or so, your Doctor will advise for X-ray or CT scan of the skull bone for ruling out any other causes that are rare to be noted harbor can apply liquid provide iodine, get started on Ibuprofen if it suits her and excision of the lump to get rid of the part that is not a normal part of the body and get a proper histopathological diagnosis. Excision may get the headache cured; if not needs further evaluation by a Neurosurgeon and further management. </s>
