I would also like to welcome you to this site. You will learn so much information and communicate with other people who know exactly what you are going through. We basically all share the same problems.
The earlier you start to treat this condition, the better your results will be. Your lymph limb(s) can greatly improve but will never be as before. Burning and tingling are normal as there is alot of compression going on and pressing on nerves. Weather definately does make a difference. Hot weather causes more swelling. Try to avoid your skin exposure to the sun or even hot showers etc.
Lymphedema is definately a challenge and alot of work to keep things under control. You are far from alone, so don't get down on yourself. Life can be quite normal and joyful. We are here for you.
