Brief Answer:
You can expect a nearest possible diagnosis

Detailed Answer:
Hi, Nice to hear from you.

The answers provided to the questions by you will make me think and arrive at a closest possible diagnosis. Because its practically not possible to pin point the diagnosis of a lump or swelling without direct clinical examination and laboratory investigations.

Based on the information you have provided in the query - "a lump on my right calf near the large bone that's sore to the touch that's starting to turn black and blue" without any history of injury could be
* bony swelling if its hard in consistency or a soft tissue swelling if its not hard
* as its sore to touch, it could be an inflammatory swelling
* as it is turning black and blue , it could be a soft tissue Hemangioma

So, a detailed direct clinical examination along with appropriate investigations like FNAC, Open biospy and MRI scan may be needed to establish a correct diagnosis.

Hope I have provided you a reasonable explanation for your query.

Happy to help for any further clarification.

Good day
