Many months ago I sneezed real hard and had a sharp pain real quick in my lower left side after that when I would for instance move around certain ways it would hurt and after a while it went away no more issue then here in the past few months I was sick for over 5 to 6 weeks with stuffed nose along with coughing and now that's better but after I figured I was better I was scratching my left side of my neck the same side of that pain I had months before I now feel a bump only on the left side of my neck it's not painful at all and it moves around when I touch it should I be worried my family says it most likely a fatty tissue I looked this up and many say u get lumps in neck cause when ur sick some of the bacteria is caught in lymph nodes and swells during the healing of an upper respiratory infection which I had all the symptoms of got any answers for me regarding this
