<s>[INST] My 2 year old has a lump on her thigh in the region where she had her jabs, only on the right leg. It is about the width of a golf ball and purtrudes about a inch. It does not move, it doesn t cause pain but she doesn t like me touching it. My daughters last injection in this area was when she was 5 months old. Is it possible this is still due to her injection or could this be anything else? Thanks in advance. [/INST] Dear Sir/ Madam,Thank you for posting your query at healthcaremagic.comMany a times, at the injection site the drug administer may not have been absorbed. It might have gone for encapsulated fibrosis. If still remains like that, lump should be excised  at earliest.I advise you to see a pediatric surgeon who would guide further.Please revert back if you need any further information.With best wishes,Dr, Vishwanath Patil </s>
