I don't think it's from typing, but it might be since I have been doing much more of that than usual lately(!)
Only a doctor could give you much of an idea. You would need, at least, someone to take a more specific history and do an exam.
Involvement of all the tips is not usually a neurologic problem because of the way the fingers are innervated. Circulation issues (Raynaud's would be an example) can do this but are usually associated with color changes. Arthritis can do it but would give symptoms fairly specific to the DIPs (the most distal finger joints) if the pain is "at the tip." An assortment of things can make the pads hypersensitive, and you can have problems in the pads themselves.
In short, it's unlikely any guesses here would be anything being WAGs, and probably misleading at that.
