suggestions required on Vitamin D deficiency and joints pain

Ouch! You haven't 'recovered' very fast - you haven't recovered at all. All you have done is correct your circulating level of vitamin D. The damage to your skeleton will likely take months to sort out. 

The bone and joint pains in vitamin D deficiency are caused by osteomalacia - the softening of bone as calcium is removed by other metabolic processes and not replaced. (This is known as rickets in children.) The bones, which have become softer especially at their ends, get squashed when loaded with your body weight at these soft points and stimulate pain signals from the nerves. 

Your body will hopefully be responding to the vitamin D now and remineralising themselves, but it doesn't happen overnight. Professor Michael Holick, who is a world authority on vitamin D, says that it takes six months to a year to reverse the bone softening of osteomalacia. You can find several informative lectures by him online if you are interested. 

I'm not sure where you are based, but most UK doctors have been advised to prescribe vitamin D long term in cases of deficiency. If he or she won't, you can buy it yourself as a vitamin supplement. 

Your swollen middle finger doesn't sound like a consequence of vitamin D deficiency - you could have another form of joint issue going on at the same time, and I would pursue this separately.

The "sunshine" vitamin is a hot topic. You may have recently found out that you are deficient or know someone who is. It's shocking for most people when they have never had a problem before and believe nothing has changed to make it a problem now. The truth is that a lot has changed, and vitamin D deficiency and insufficiency is now a global public-health problem affecting an estimated 1 billion people worldwide.

The most well-known consequences to not having enough vitamin D are rickets in children and osteomalacia in adults. These are far from the only problems associated with a vitamin D deficiency. The consequences are numerous and include skeletal diseases, metabolic disorders, cancer, cardiovascular disease, autoimmune diseases, infections, cognitive disorders, and/or mortality. The majority of our knowledge about vitamin D has been discovered over the past 15 years, and with the growing issue of deficiencies, more health connections with vitamin D levels are being made. Correcting vitamin D deficiency is not as simple as taking a pill or getting more sun. This article will teach you all that you need to know about the benefits of achieving and maintaining optimal vitamin D levels.

Vitamins are considered essential nutrients because either your body cannot make them or they are made in an inadequate amount. This means you must provide them through your diet or by taking a supplement. They are essential for your health, and when you are lacking in them, there may be health consequences and diseases.

I'd keep taking the vitamin D supplements but in a smaller dose as the body (bones) can take up to a year to recover from severe vitamin D deficiency, regardless of your "normal" levels now. It's called maintenence and a dose of 1,000 IU a day or getting 15 minutes of sunshine each day will keep you from becoming deficient again... unless there's an underlying problem such as alcoholism or a stomach disorder which stops the body absorbing nutrients, which doesn't seem to be the case here. If your finger continues to give you any problems, then ask your doctor to refer you to a specialist for further testing. 

Best of luck. x
