I am trying to gain some sort of understanding of this horrible condition before i see my doctor for a blood test ! and i hate popping pills!! feel like im rattling.. i dont usually take a thing!!! and i cant sleep and i shake, and feel dreadfull, im afraid to eat in case i put on another stone,, can someone help me understand this condition as my legs swollen and i seem to be getting another symptom by the day this is all very very scary !! im off sick till the end of the month ,,another thing i dont normally do,,,,!!
