Good Afternoon Everyone, Part of me wants to freak out and the other part of me is trying to stay calm. With that said about a week or so ago i felt a soft squishy spot above collarbone (in the hollow dip location). I didnt think much of it, passed it off as a fat pocket since i have put on some weight, and the center of collarbone, where they connect, is squishy too (this has been there for months). But where my concern comes in now is that the spot is now more defined and bigger all around. It doesnt hurt and is still squishy. Sometimes i feel like there is something in the back of my throat. Another symptom that has surfaced is heaviness on my chest, deep breathing either hurts or i start coughing. I also have fatigue (majorly) but have chalked that up to fibromyalgia. Could this be a chest cold or some other type of sickness? thanks.
