For the past three days I have noticed a fluttery feeling in the left side of my chest. It is very subtle and I only notice it when I "tune in" to pay attention to it. When I am busy I completely forget about it and it is only I am having a quiet moment or when trying to sleep at night that I remember it and start paying attention to my chest to see if I can still feel it that I can then feel it.
I am not sure whether it is coming from my heart or breast but, to me, it feels like the sensation is not deep enough to be my heart but I am not sure. It gets worse and builds up when I lie on my left side which compresses my breast and sometimes the fluttering sensation moves from my chest to almost near my armpit so I do feel like that suggests it is my breast?
I have had a fluttery feeling similar to this in my right breast before several months ago but ignored it as it wasn't on the same side as my heart, whereas with this being on my left side it is making me more anxious. From what I can remember this fluttery feeling occurred during ovulation and that is where I am at in my cycle at the moment so I am not sure if it is hormonal. Also during my last period both of my breasts were a lot more heavy and painful than usual so I am not whether the fluttering could be a result of that and whether my hormones are just a bit off at the moment.
I do suffer from anxiety and have been under a lot of stress recently so I am wondering if it is anxiety. However my anxiety is making me so hyper aware of every sensation in my body which further aggravates my anxiety. I am on such high alert I can feel sensations I wouldn't normally like stomach movements. I feel small muscle twitches that I wouldn't normally feel.
Other than that I feel completely fine in myself. I am in my 20s. I drink one cup of coffee everyday and that is it. I'm not on any medications. Not pregnant.
Does anyone have any advice?
Thank you
