I just got diagnosed with pots a month ago. I have the same issues. I am 34 and a nurse. My hubby wants to get me a shower chair. This diagnosis is unfair to all of us. We can only do one event a day sometimes because our bodys just can`t take it. I was told by a doctor at Mayo to turn the water cold before you get out. Sometimes it works for me. I wish I could tell you that if you just keep walking you will get use to it. But sometimes that is not the case. This sounds bad but be gentle with yourself. Have you friends and family walk slower. MY family and friends for get and I end up going home because body can not take it. Don`t loose hope I am going to Chicago to talk to a doc in ChinaTown who is an expert in holistic medication. I will let you know how it goes. You can find me under Shadowhat.
