Languages symptoms and conditions

I'm 52 and I've been on Warfarin for a year and a half after having a mechanical aortic valve replacement performed in China, with an American titanium valve. I went through some serious episodes of blood thinness, then moved from northern China to SE Asia. 10 months after being here, I continue to work long days, but my energy is all over the place. When thunderstorms come in (daily) I have migraines, but this may be due to head injuries years ago. The main problems for me are up and down episodes of energy, and when the energy is low, I go pale. Pain in my knees and feet when I don't walk enough (maybe an hour sitting), or walk too much (maybe an hour walking) and very rarely what I think is something like aphasia -- the right words don't seem to come out on rare occasions -- maybe too many languages crawing in my head :). I used to walk an hour and a half per day -- not any more. Blood is on the thick side -- surprising because the diet her is very low fat. I want to get back into walking, get my strength back. I also have heard of socks that help in blood circulation. If I had a name or a brand, I could probably find the product in Thailand. Any idea, thoughts? I'm very frustrated.

I would like to know who is NOT experiencing side effects from Singulair.
We are not.
My 7 years old started Singulair three months ago because of allergy issues. She had asthma attack every other week, running nose all the time, she was so miserable, she missed many days of school and she couldn't exercise .Since she started to take SIngulair her allergy improved, no more asthma, no more running nose. SIngulair did not change her way to be. She is doing very good in school (she is above the average..) she does piano, ice skating, she is purple belt Tae Know Doe, speak two languages, she is doing great in everything. Of course she has her "bad moments" but which child does not?
I tried homeopathy, but it did not work, she got worst and worst. I was supposed to give SIngulair to my daughter a year ago, I did not because I was afraid of the side effects. But I wished I had started before because I could have avoid so much steroids since she had asthma most of the time. The doctor convinced me to use this medicine when she said " You think SIngulair has side effects, yes sometime it does, but do you know the danger of using steroids so frequently in a little body?" Then I thought I had to give a try. I am glad I did. Of course I keep watching my daughter behavior closely and reading all the possible side effects of this medication. I forgot to say that beside singulair my daughter is also taking Pulmicort, two puffs once a day.

My 3 year old is on 5mg of singular daily for her constant allergy issues and has had NO trouble at all with it. Her personality has not changed.. she's happy, outgoing, friendly and MUCH better than she was before she started the medication. Prior to starting she was constantly dripping from her nose, she had both ears filled with fluid, had bags under her eyes and was tired and grumpy all the time, due to allergies we could not get under control with other over the counter or prescription meds. Since being on Singulair she's been 100% better than she was. I'm sad to hear that others are having so much trouble with it, but I can say that I am happy my little girl is feeling better.
