Thanks for using health health acre magic for posting your query.
Please dont feel depressed. Modern science has progressed so much that almost all illnesses are curable. The lump you are talking about appears to be lipoma
. They are very common and are not troubling. I hope it is not painful or increasing in size. You should visit a surgeon or a gynaecologist for this problem and not a orthopedician for your problem.
Hope I am able to solve your concerns.
If you need a detailed answer, I would be more than happy to help you.
