hi about 1 month ago i had a pea sized lump show up out of the blue, it doesnt hurt or ache at all, it seems like its DIRECTLY under the skin, it doesn feel like its attached to anything like a bone or lympho nodes, i can pinch it in my fingers and move the pea around, i can "pull" is off up and all around. if a lymphnoid has a tumor on it would i be able to pick this thing up off of it like that? when i pull my scalp the lump moves with it, if it was the lymphnode, wouldnt the pea stay still and the skin would glide over it?? god im scared

please advise, i have no other symptoms at all, i am just worried cuz my mom has nhl and i think im a worry wart now

, so i guess what im asking, as i discribe this lump, does it seem to fit the bill as a lymphnode lump, or maybe just something under the skin, its perfectly round and smooth, same color as the reast of the skin, please help also there is NO sweeling at all in these or surrounding nodes
