TQC, I have recently started swimming again after a break of a few months. Swimming is making me dizzy. Sometimes dizzy enough that when I come out of the pool, I can't walk in a straight line. Why is this and what can I do? If it's relevant, I've been swimming for 20 years without these symptoms, I swim on my back and breast stroke and I put my head underwater but my ears don't hurt and I never feel like I have water in them and I've never had swimmer's ear. Any ideas?
