About three weeks ago I noticed that my ring finger, middle finger and my index finger were somewhat difficult to move. I noticed that those fingers would not spread apart like the fingers of on my other hand and when those three fingers were spread as far as i could get them they would not move at all towards the direction right. Within about a week of that I realized my hand no loner was straight and sunk downward in the middle on the backside of my hand. Within another week and until now there is a lot of atrophy to the left of the base of my thumb. There is no pain nor numbness and I do not detect any strength loss. Also, the ring finger knuckle sticks upward more than the other fingers. The picture is not great but hopefully you can see the areas in which I am speaking of. I do not have a neurologist appoint until the end of May and am beginning to worry that I may lose use of this hand if I do not do something a little quicker. There has been no injury to the hand or the arm. Two questions I guess what could this possibly be and should I be trying to get a quicker appointment? I am 47 overweight by about 25 lbs I take no meds except for some edema that I get in my legs and feet (no one knows what is causing that) called Triamterene which also helps with high blood pressure.
