Can anyone help,

I have been having issues within my house, it started (as far as I know) from my couch, and seems to have also spread to my bedroom, but I have no idea what is causing it.

Basically when sitting on the couch you will eventually feel itchy particularly in areas in close contact with the couch (legs etc but also your arms and body). But there is no evidence of the typical red/brown staining you would see from Bed bugs, I have actually put tissue paper under my bed and under a couch cushion now to see if I can see this.

Does anyone have any idea what else this could be?
