Hi,
Accumulation of fluid around the thumb joint can occur due to a variety of reasons, including
injury, inflammation, or infection. In your case, it is possible that the injury from the fall caused damage to the joint, resulting in fluid accumulation and swelling.
To get used back of your thumb, it is important to seek medical attention from a healthcare provider who can properly evaluate and diagnose the underlying cause of your symptoms. Depending on the severity of the injury, treatment options may include rest, immobilization,
physical therapy, or surgical intervention.
In the meantime, you can try to reduce swelling and inflammation by applying ice to the affected area several times a day, taking over-the-counter anti-inflammatory medication such as
ibuprofen, and keeping the thumb elevated whenever possible. It is also important to avoid activities that exacerbate your symptoms and to follow any recommended treatment plan provided by your healthcare provider.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Priyanka, General & Family Physician
