Without the ability to examine and obtain a history, I can not tell you what the exact cause of the symptoms is. However I will try to provide you with some useful information.
Tingling sensation in the hands and fingers has a large differential. the sensation occurs on the medial fingers (pinky and half of the ring finger) and medial aspect of palm, it may be a neuropathy from the ulnar nerve. This nerve is also known as your “funny bone” when tapped or hit. It has several sites of compression along its course – one site being at the elbow. Classically, it may be a truck driver who rests elbow on window/door. It should also be mentioned that with rapid weight gain or weight loss, the ulnar nerve or median nerve (which causes carpal tunnel syndrome) can be compressed and cause their neuropathies.
I recommend that you follow up with your local neurologist. He/she will perform a specific neurological examination focused on the ulnar and median nerves. The neurologist may also elect to perform an EMG/NCS to evaluate the motor and sensory components of the median and ulnar nerves as they travel to the wrist.
Thank you for this opportunity to answer your questions, I hope you find the information I have provided useful, good luck.

Sorry, only tends to happen when I am standing or laying for some reason
Just noticed when I put my big toe over my second toe my left foot will tremble, this does not happen with right foot. Not sure if this has always happened. Is this normal?
