4. Medications
Certain medications may increase the likelihood of developing trigger finger – especially those that act on the metabolism. This might also be true of performance-enhancing drugs and even recreational drugs in some instances.
For example, some anabolic steroids will work by increasing testosterone (the male hormone) but this can then be metabolized to create extra estrogen. While the user’s male traits are exaggerated, so too are their feminine traits. This can lead to a number of unwanted side effects that run contrary to the intended use.
One such side effect is swelling, which can lead to a look of ‘puffiness’ through water retention and can also cause joint pain and discomfort.
