I don't know where to go from here.
Abit of context..
Beginning of November I had bronchitis. Was given anti biotics and it cleared up within a couple of weeks.
Fast forward a couple of weeks I started getting pain left side & centre of my chest, more of a stabbing sharp pain which was very intermittent. I called doctors, the nurse practitioner listened to chest/heart rate, told me I had anxiety, I told him I didn't (i work in mental health) and he asked me what I was worried about, I said my heart, he told me his checks didn't point to anything and sent me home.
The following week (may or may not be related) my hands, feet and nose were/still are, as cold as if they have been in ice. Developed chilblains on my toes for first time ever twice over throughout december/january. My feet, particularly my toes are grey/blue anytime I have a shower/bath or go out in the cold (even with thick socks) was also feeling very tired. Chest pain continued but was increasing in terms of not so intermittent.
Come January, 2nd doctor tested iron levels because of blue toes and sent me for ECG as I mentioned the chest pain. I looked at ecg, It said at top, non specific ST abnormalities. That was 10 days ago. On that day doctor confirmed iron levels low, started iron tablets. (Had low iron levels several times)
Fast forward 10 days, nurse practitioner whom ordered ecg has been off sick, no one called me with results. Over yesterday and today the pain is in my shoulder blades, shoulder, jaw. It is stabbing intermittently in my chest with feelings of heaviness & pressure and a dull ache. Called docs again, got a 3rd practioner. They said ECG is normal, got me in again, listened to chest, told me they don't think it's anything and to take painkillers and call back in couple of days (for the fourth time) Got asked again, what I think is wrong.
I have called nhs 24 tonight for further advice/opinion. They said to listen to gp amd that it isn't serious enough to go to A&E. Does it sound like nothing? Should I push further with them? I am 36 and genuinely worried about this.
