Hi,
The symptoms you described, such as sharp
tingling, blue knuckle, and swelling in the middle finger, could be caused by various factors, such as trauma, injury, or a medical condition.
Trauma or injury to the finger, such as hitting it against a hard surface or accidentally closing a door on it, can cause a blood vessel to rupture and result in bruising and swelling. This type of injury usually heals on its own, but if the symptoms persist or worsen, it is advisable to seek medical attention.
Another possible cause is a medical condition such as Raynaud's disease, which is a condition that causes blood vessels in the fingers and toes to narrow, resulting in a decreased blood flow to the affected area. This can cause tingling,
numbness, and discoloration in the fingers, especially in response to cold temperatures or
stress.
In some cases, blue knuckles and swelling in the finger could be a sign of a more serious underlying condition such as
arthritis or an
autoimmune disease. It is important to consult a doctor if the symptoms persist or worsen, or if you have other symptoms such as joint pain,
stiffness, or
fatigue.
In any case, it is advisable to rest the finger and keep it elevated to reduce swelling. Applying a cold compress can also help reduce inflammation and discomfort. If the symptoms persist or worsen, it is best to seek medical attention from a doctor or specialist.
Take care. Hope I have answered your question. Let me know if I can assist you further.
