For this feasibility study we will determine the demand as measured by the number of patients accepting the treatment vs the total number of patients offered enrollment. We will determine the percentage successful completion of the 40 prescribed treatment sessions as the primary outcome variable. The results of the symptom questionnaires obtained at the conclusion for HBOT and by follow up telephone survey at 1, 6 and 12 months following completion of HBOT will be the secondary outcome variable. Finally, adverse events will be gathered on this patient population as per routine clinical practice. The incidence and severity of otic barotrauma, hyperoxic myopia, confinement anxiety and generalized seizures will be determined and compared to the same events experienced by the general hyperbaric patient population being treated during the same period of time.
