The OP is asking for tech details to inform a purchase. This is after consulting with a medical professional.
Most of us in here aren’t medical professionals. None of us knows exactly what the OP’s malady is. None of us have examined the OP. Nobody in here has a leg to stand on, second-guessing the OP.
