Hi, dear I have gone through your question. I can understand your concern. She may have some soft tissue tumor or bone tumour. It doesn t look like emergency. She can take analgesic drug for pain relief. After one or two days she should go for ultrasound study or x ray accordingly. If needed go for biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using health care magic. Wish you a very good health.
