Swelling and thickening of finger joints may be caused by venous return obstruction, osteophytes or rheumatism.
1. Venous return obstruction: patients with thrombosis or venous injury can cause venous return obstruction in the fingers, which may lead to thickening of finger joints, swelling, and elevated local skin temperature and other symptoms.
2. Osteomalacia: Osteomalacia is mostly seen in middle-aged people, and the finger joints with osteomalacia can produce mechanical stimulation to the surrounding soft tissues and lead to symptoms such as joint swelling and pain.
3. Rheumatic diseases: mixed connective tissue disease, rheumatoid arthritis, scleroderma and other rheumatic diseases can also involve the finger joints and lead to joint swelling and coarsening.
There may be other reasons for the swelling and thickening of the joints of the fingers, and it is recommended that patients go to the rheumatology and immunology department of regular hospitals, orthopedics and other related departments for detailed consultation and treatment in accordance with the doctor’s instructions.
