I know I have been neglecting myself lately, not getting enough sleep usually the most 4 hours and have 3 kids to take care of one only 2 1/2. Also just last week was feeling a heaviness in my chest but chalked it up to stress over putting our house up and wanting to relocate. I also have mitral valve prolapse so I thought the heaviness could have been due to something with that. Anyway the heaviness in my chest went away and last night I noticed the front of my left shoulder and collarbone/chest area was all pins and needles. I happened to be downstairs on the computer and my basement tends to be a little chilly so I just thought it had to do with that. Then I noticed the next day it still felt like that and I wasn't downstairs. Is this something I should be concerned about? I am going to call my doctor tomorrow, it happened to be late Saturday when this first happened and then Sunday so the Doctor wasn't open.
