Hi. I am new at this. I had ACDF surgery on the 5th of March and have developed a hard lump under the incision. It is slowly reducing in size but still have me concerned. This lump seems to be pushing on my throat making it hard to swallow. My diet is basicly liquid to this point. I see my NS in two days and I am sure he will be able to let me know what this lump is. Has anyone had this same expierence? Hoping someone could tell me this lump is and when it will go away!
