An interesting experience ~ After a long day at work on a rainy day, I opted for a soak in the tub. When it came time to get out, I used my usual maneuver... left leg over right, turn and land on left knee, being careful not to put my weight on the right knee. It's quite a contortion but it usually works. Only this time, before I could push myself up, I got a major cramp in the back of my thigh. PAIN!!! I had to push through... it wasn't pretty and it reminded me of how vulnerable one can be when living alone. Which leads me to wonder... how long on average before I can kneel on this thing? Can I ignore the pain and put my weight on it if I have too? What has been your experience?Thanks in advance for your feedback.
