Lump in back of neck below hairline
I am having this lum/bump/tight knot on the slightly right side on back of the neck, below the skull.
Its been there for over 2 months. This results in chronic ppain the the neck area, although the pain is not severe, but rather dull.
The knot or lump is more long than it is circular. On pressing it, the area flattens and seems that there is no lump. after sometime, it reapears. on palpating, it does not feel like a sponge or something. its more like a hard tissue below the skin.
Would apreciate if someone can provide some solution to this. Is it arthritis, lymph swelling, muscle spasm, tumor.
