The thing with fingers is this - they are basically very static structures, biomechanically. You load them, and they either take the load, or something breaks (it may only be a few fibres), hence injury. Similarly, your options in terms of treatment are either a) surgery, or b) avoiding exacerbating the injury and gradually increase the loads placed on it while it repairs itself to minimise scar tissue build up and ensure good alignment of the fibres as it heals.
In your case, you don't need surgery. Which leaves you with option b). As I put in my previous post, the rate at which you increase the load is very subjective, and is based on symptom response. If you aren't in denial about it hurting when it hurts, and if you are patient and systematic, you should be able to manage this yourself. In fact, nobody else can really manage it for you, they can't feel your symptoms.
Finally, a question I always ask people is "is it getting better?" if the answer to this is "yes", then you almost certainly have not a lot to worry about. However, obviously if you have any doubts about it, get it checked out professionally.
