Two things might be going on.
The wrist problem sounds like a nerve impingement, most probably at the cervical spine...neck. I would want to see an MRI if there are any findings on exam, such as an abnormal reflex in that arm. You will need an examination to sort this out.
Such nerve impingement at this location could cause pain in the neck, the arm, the shoulder and even the back down to the shoulder blade.
The other joint pains need to be considered.
disease causes asymmetrical arthritis, so a sed rate and an ANA panel [blood tests] can rule this out.
Also an RF [rheumatoid factor].
problems can cause arthralgias--joint pain--so a comprehensive metabolic panel, a CBC and a thyroid
panel should also be run.
A disc problem in the neck plus an illness such as fibromyalgia could also explain all of this.
With the occasional wrist drop, I would get examined as soon as possible. If necessary, an EMG can also be done...tests the neuromuscular junction.
Good luckGood luck
