Hypotension = low blood pressure, not high, it's really only an issue if you don't control the low blood pressure, just like hypertension, it's very conditional upon the diver.
RE: Scoliosis would only be a problem if you were required to carry the tanks/weights to and from the dive site that is really far away from the parking/gearing up area, I'm sure the instructor/DM will assist you in carrying the majority of the weight ie. the tank, but sidemount might be something to look into for future dives!
