I'm wondering if wearing a piece can cause a headache or lead to clouded thinking, either due to the pressure from having the system on the head stretched for long periods of time, or from the glue/tape residue itself (which can cause redness and irritation - perhaps allergic reactions?). It might be rare, but I'm wondering if it does happen - I happen to be hypersensitive and wondering if my recent headaches could be due to this, as opposed to the more likely reason - stress from finals coming up. Thanks!
