I'll start by saying I'm ignorant on hammocks and have a bad neck due to a car injury, but therapy has helped make it 90% pain free now. I'm a side sleeper and I've always liked tents more but I really don't sleep well in my tent (BA Copper Spur), because I can't pack anything large enough to give me a good 5-6" of pillow for neck support. The cocoon pillow was not the answer, nor were the down ones I tried that compress down to 1/2" thick under your head.
ALL THAT ASIDE, my thinking is maybe a hammock would put my neck in a different position that will make it easier to get comfortable. Now I know the obvious thing to do is go check them out in person. I live in NE Ohio, which is a hiker's black hole. Everything escapes here except snow unfortunately! The only place I'd know to look is REI, and the closest one is a few hours away. I'm looking for anyone who has any neck issues to comment on if hammocks were better or worse for you. It would awesome to find a local person on here who owns a hammock that would let me check it out for a few minutes. Just looking for some advice so I can try out all my options, because otherwise my hikes will continue being sleepless and painful. Thanks in advance!
