What Does Pins And Needles In Fingers While Grasping Stuff Suggest?
Neurological evaluation needed.
Detailed Answer:
Hi and thanks for using HCM.
In my opinion, your condition is not related to heart or cancer disease.
It is a neurological issue that needs more evaluation and tests.
If I were your treating Doctor, I would have ask for more information about your concerns; how about hand and arm muscles strength, how long last pins and needles, overall time of your symptoms, are pins and needles accompanied by hand shaking or muscle fibrillation?
Besides this information, neurological examination, nerve conduction study (EMG) and, probably spinal column MRI are needed to help the diagnostic process.
There are neurological conditions that may cause your symptoms, I will mention some of them: nerve entrapment syndromes, neuromuscular diseases, cervical spine conditions.
Of course, these are hypotheses, so there is need for you to consult a Neurologist and discuss your concerns.
Hope this helps. If you have further questions or clarifications, feel free to ask.
