My left arm often goes numb while sitting and watching tv as well as sometimes when I am sleeping. I can understand while sitting watching tv since I am often leaning or propped on my left side but do you have any suggestions on why this would happen?
Hi, the site where it goes numb is important, as you would be aware these symptoms are due to pressure on nerves, and sometimes, even if the pressure is less, the threshold of working is reduced due to diabetes, or vitamin deficiency. If I had been consulting you then, I would advise you to get blood investigations to ascertain the level of vitamins in blood, check sugar level, and see if you are developing neuropathy.
