The causes of thumb swelling and pain for no reason may include rheumatoid arthritis, tenosynovitis, onychomycosis, etc. Patients should choose general treatment, physical therapy, medication and other methods to solve and treat the problem according to different causes.
1. Rheumatoid arthritis: Cold and moist environment can induce rheumatoid arthritis and cause swelling and pain in the thumb. Therefore, we should pay attention to keep warm, avoid dampness and cold, and can take non-steroidal drugs such as aspirin, ibuprofen, etc., as well as anti-rheumatic drugs such as methotrexate, leflunomide, etc. for treatment.
2. Tenosynovitis: Long-term wear and tear on the tendon of the thumb causes tenosynovitis, leading to pain in the thumb. Therefore, we should reduce the frequent activities of the thumb, pay attention to rest, and choose physical therapy such as hot compresses, massage and infrared rays to promote local blood circulation and inflammation absorption.
3. Nail groove inflammation: trauma and bacterial infection can cause nail groove inflammation, resulting in swelling and pain of the thumb. Timely disinfection and dressing change should be given to control the local infection, and debridement and nail extraction are needed if necessary.
If the symptoms of swelling and pain in the thumb for no reason persist, you should go to the hospital in time for examination and targeted treatment after clarifying the cause of the disease, so as not to delay the condition. The above drugs need to be used under the guidance of a doctor’s standardized use.
