Hi again, recently to try and fight my anxiety I've been starting to exercise which mostly involves walking a couple of miles during the day. While walking however, I will get a tight chest which quite considerably raises my anxiety level and makes me think I'm having an Angina attack, or have Angina as a heart condition.

As a bit of extra information I'm also very unfit, I have a normal weight for my age but have never exercised properly before, maybe it's just my body getting into the swing of things?

On a slightly different topic I also get a weird cold burning sensation and ache in my left arm when it reaches over my body, to say type on my tablet when it's on my right side. This doesn't happen with my right arm if my tablet is on my left side. Sometimes my left arm just aches out of nowhere and makes me scared of a neurological condition.

Any help on both these ailments would be greatly appreciated. In a dark place at the moment in terms of anxiety and need all the help I can get.
