Detailed Answer:
Hi XXXX,
Thanks for writing in to us.

I have read through your query in detail.
Please find my observations below.

1. It is important to have a look at the x ray to know the exact nature of the black spots which you are referring to. You can upload the x ray and mark around the black spots which you see.

2. Black spots on the X ray are areas where there in increased penetration of x rays and therefore if it is in the bone then it means decreased mineralisation.

3. There are many otherwise normal areas on a leg x ray which might appear black. At the same time any condition causing the bone to lose the calcium can cause black spots.

In conclusion, black spots can mean that the area has lost the calcium if it is over the bone. In other areas it can also be a normal feature. It will help to attach the x ray and mark around the black spots which you see.

Hope your query is answered.
Please do write back if you have any doubts.
