Thank you for posting your query.
I would like to reassure you that an injury
sustained six years ago would not result into any serious problem now. So, your current symptoms are not of any concern.
The calcified area would not become bigger as such. However, if it became bigger in size, it could be an unrelated problem such as minor injury, infection, etc. Since it has started to decrease in size and is free of headache, you need not worry about it. Just keep a close watch over the affected area.
Wishing you good health,
Dr Sudhir Kumar MD DM (Neurology)
