Parkinson's Disease seems to be a conflict between the muscular system and the nervous system - thus, a perceived conflict between what the person wants to do and what they perceive authority wants them to do. This ambivalence is what causes the shaking - so you need to just go for whatever it is you want to do, and resolve any apparent conflicts in your onsciousness concerning whomever or whatever represents authority in your life at this time. Trust your trip.

MS means you have been holding yourself back from living your own life and your own dreams, because of fear of standing up to authority. Look at what was happening in your life when the symptoms began. Own your power and top making yourself helpless in your own consciousness, and replace "I can't" with "I Can." When you do that, the means to how to do it can become evident. Tony Robbins is a good motivator, and you can see if you can use some of his material. Silva Method is also available in your part of the world, I am sure, as is my book about healing, Anything Can Be Healed, published by Jaico.

For freedom, just make decisions about what you should do, not what others should do. In a situation that is not a happy one, do not decide what the other should do, just what you should do. In looking over things from the past, do not decide what others should have done, but what you could have done differently.

Honor freedom for others and you will own it for yourself.

Be real. Be who you really are.

Freedom is power.

For security - trust your trip.

Hepatitis C - Anger

Genital Herpes - Feeling that sex is dirty. Giving yourself reasons to not have sex. Perhaps, enforced monogamy.

High Blood Pressure - Tension in the area of relationships, people close to your heart. That could be a partner, parent, sibling, or offspring.

Look at what has been happening in terms of the root chakra areas of your life - money, home, job - and which matters are "itching" to be resolved.
