For the past 5 months I’ve been experiencing all kinds of symptoms, fast heart rate, nervousness, chest pains, muscle/body aches. I’ve been to 3 different doctors. Got bloodwork twice, got ekg twice all came back normal. Only thing that wasn’t normal is that my vitamin d levels are 22/30 but I’m taking vitamins for that now. These past two days i haven’t really felt nervous but I have this weird feeling I can’t Explain, I almost feel nauseous/lightheaded on and off throughout the day. Also my head feels heavy. It’s a weird feeling and it’s on an off in the day. Is this part of anxiety? I have no reason to be anxious. Also wanted to mention I had a baby 5 months ago. I’m 26 years old.
