I am looking to get a PPL to be more competitive for guard/reserve units but have came across a strange medical issue involving 0g/.5g pushovers and rapid descents.
Whenever the descent begins, my lower abdomen and legs immediately tense up and I'm almost paralyzed. For example, we did a performance takeoff and I was completely fine on the climb, but the second he went to level out my quads and lower abdomen locked up and I felt like I was leaning back in the seat with those muscles entirely tense. I am completely fine doing 2G banked turns, steep climbs, and dealing with turbulence and other normal flying maneuvers. However, for whatever reason, these steep descent and the pushovers do this to me. My core, lower back, and legs were actually sore after flying yesterday and encountering this. I've had this happen to me in a car when going up and down a deep bump quickly at speed, and also on a snowboard in the same scenario; however, in these cases, it only is an uncomfortable feeling in my lower abdomen and I never experience the leg lock or even the core lock. My instructor was concerned about this and will not let me solo unless this issue can be fixed (rightfully so).
Has anyone seen a trainee do this/dealt with this issue themselves/even just heard about this issue? We were thinking it may be a rather unique vasovagal reaction. I'd really appreciate any insight y'all have on this matter.
