Lots of people have been posting about ALS since the new year and they all have that heavy, buzzing, tingly feeling in a limb or several limbs. Everyone that has had a neuro test and/or EMG has gotten a clean bill of health. So the logical conclusion is anxiety. I know it’s hard to believe, but think about the way you have felt the last few weeks. Your anxiety has been sky high. It isn’t surprising you are feeling new sensations because of your anxiety. If you can, try to alleviate some of that stress and adrenaline with exercise, yoga, meditation, massage, etc...Talking to someone like a counselor or therapist would also help. Getting control of your anxiety and changing your thought patterns around the sensations you have does help.
