Hi Grammadur,
Welcome to the forum. I am sorry you have RSD and going through the by-products of RSD.
Are you keeping a daily diary? This will assist you in keeping your meds in check;also, it will be useful to have a diary to record your experiences.

A secret diary, that is for your eyes only. A place to vent...a place to write down what symptoms are popping up. Use the diary to remind you of questions you may have for your doc.
The meds can cause memory loss;however, the brain is effected by RSD. The entire body is effected by RSD. I do a lot of research.
You can always vent here..I am available anytime you wish to chat.
Stay Positive!
