I have been having this weird tingling sensation in fingertips. Not all but the big toes and the index fingers in my hand for sometime. Now, from yesterday, there is a slight pain in my left big toe. It's not due to any injury, it just feels that someone is pressing certain nerves there. I am not a diabetic, no history of any major or minor disease, I also undergo routine health checkups and there has not been any thing to take note of except uric acid around 6. I was trying to read something about this on internet when I came across the term'paraesthesia' There is no numbness in the affected part and currently in not under any sort of stress either. Please suggest the proper course of action.
