There are many conditions which can lead to your symptoms like a neurological or circulatory problem. Your symptoms could be suggestive of ulnar nerve entrapment or Carpal tunnel syndrome. In this condition the median nerve, which runs from the forearm into the palm of the hand becomes compressed. The underlying causes could be diabetes or arthritis .Avoid activities that may worsen symptoms. Immobilize the wrist in a splint to avoid further damage from twisting or bending. The cause of ulnar nerve entrapment is swelling of the elbow, which may be due to arthritis or other medical conditions, cysts, prior fractures in the arm or bone spurs. A clinical examination and MRI findings may help. See a neurologist. Do keep me posted.
Best luck and regards!
