Updated April 11, 2017. Speech pathologists, officially called speech-language pathologists and sometimes called speech therapists, work with people who have a variety of disorders that include the inability to produce certain sounds, speech rhythm and fluency problems, and difficulties with their voices.
Some of the most common causes of swelling fingers include arthritis, fluid retention, and pregnancy. In addition, finger edema can be caused by cardiac problems, abnormal kidney function, and allergies.
The swelling makes it difficult for the affected tendon to slide through its membrane (tendon sheath), causing the pain and stiffness associated with trigger finger. The swelling can cause a section of the tendon to become bunched into a small lump (nodule) at the base of the affected finger or thumb. If a nodule forms, the tendon can get trapped in the tendon sheath, causing the affected finger or thumb to become temporarily stuck in a bent position.
