Lump on my shin?

Don't ask us. Go see a doctor!

And don't wait around to do it.

If it is totally harmless, waiting might not be a problem.

But there are fatal illnesses that are easily cured if caught early. If you have an early detection of one of those, the last thing you want to do is wait (just ask Steve Jobs).

Please meet a general surgeon/local homeopath/dermatologist for physical examination, relevant investigations, accurate diagnosis and permanent cure by medication and or surgical interference. You will need x-rays and perhaps an MRI scan.
