Swelling and pain at the end of the finger can be caused by mosquito bites, osteoarthritis or tendon cysts.
1. Mosquito bites: After being bitten by mosquitoes, the skin at the end of the finger will become inflamed due to venom and saliva injection, which will lead to swelling, pimples, itching and other symptoms.
2. Osteoarthritis: Osteoarthritis is a common joint disease in the elderly, which can lead to focal defects of articular cartilage, subchondral bone changes, bone redundancy and synovial hyperplasia of the joints, which can lead to symptoms such as joint swelling and pressure pain. Therefore, the swelling and pain at the end of the finger can appear in osteoarthritis patients.
3. Tendon sheath cysts: tendon sheath cysts, i.e. cystic swellings in the tendon sheath, are common in women, with slow onset. When they occur at the end of the fingers, they may appear as round, pushable lumps, which may cause discomfort such as soreness and swelling, and affect the joint activities.
There may be other reasons for the swelling and pain at the end of the fingers, so it is recommended that patients go to the rheumatology and immunology departments of regular hospitals for further consultation and treatment according to the doctor’s instructions.
