<s>[INST] Dear Dr,My  5 years  toddler  have fall down from a bed and bump her head  (left side above ear -the corner) on a hard floor.  Immediately I spot a huge lump in her head.  I had immediately applied wrapped ice on her head.  She did not cried much and fall asleep.  No symptom of vomiting, etc.  However I took her to GP on the next day and was advised to keep an eye on her for several days.  Seventh month passed and in the first 6 weeks about 50% of the lump has reduced.  The rest 50% retained till today ( not very obvious but the lump can be noticed easily if any one touched and compared her right and left head corner.  She did not complained any pain when I pressed the head after 2  months.  But now she is having chicken pox and she is complaining  about mild pain in the lump for the first time in four months. Any advise from you will be highly appreciated. `Melly` [/INST] Hi, Dear , Thanks for the query to My Chat Doctor Clinic. I studied your query in details and understood your health concerns.
