I was just certified this weekend. Everything was fine after my dives and my dives went well. Did not ascend too quickly. did not hold breath. Starting the next day I was light headed, had a headache and was nauseated. Today the headache and nausea are gone but I feel a little "floaty" and have a mild pain in my chest on the right hand side. Anything to concerned about? I am planning a dive in about a week and don't want to go if there is a problem. Thanks!
