equilibrium

Lately, I'm having a horrible time with my equilibrium. I constantly feel like I'm falling especially sitting in a chair without arms or standing; I've taken to holding the table or whatever to help me stay oriented. I don't know if it's the weather? But I feel like my progress is backpedaling! I think I am getting stronger and my endurance might be improving; it's hard to determine the endurance because I'm wasting so much energy trying to counter the messed up equilibrium. Hopefully, restarting PT will help.
