My Mother is in the middle of a series of 40 HBOT treatments right now... she's a bit claustrophobic... so getting the chamber is a bit hard... but the people at the center she's going to are great about it... she's noticed some positive changes... her "cold" leg is warmer at times... she's using her cane less and just last week started walking up stairs one stair per footstep vs. both feet on a step to the next... small improvements... but we'll take any improvements!
