We study obstructed deformation problems for two-dimensional residual Galois representations arising from weight~2 newforms of level~N. Using Poitou-Tate duality, we isolate local and global sources of obstructions and give concrete criteria for when they occur. In several cases we also describe the resulting universal deformation ring explicitly.
