I get the throat stiffness too..Which makes it difficult to swallow. Icant feel a lump eithr but it feels as if my throat is really tight.
Ive had this for sumtime...Doctr said it is common symptom of stress n anxiety, which causes throat muclses to tightn/contract. Doc said when stress settles so will the throat thing.
Dont worry urself about it..Cause it is caused by stress.. And u worryin about it will b counter prodcutive.
Its jus a viscous cirlce.
How long have u had it for?
