My son, age 45 has recently been diagnosed with Postural orthostatic tachycardia syndrome. He was always a very healthy, active person, and this has almost left him homebound. Would like to know of any natural or alternative remedies anyone has tried to help this problem and get this man back on his feet and enjoying life again. He has a family with 4 children and would love to be doing things with them. He is not able to work and needs to also. Thanks for any help you can supply.
