I will start by saying I'm under health investigations so this is just for some ideas. About 18 months ago I woke up with really tight ankles which I knew was odema. I was also tired and breathless so had hadtests for heart failure and circulation. All fine ( or fine enough I guess) then I have nerve conduction studies, scans on my hands, mri all ok. Since then my face is also swollen on waking. Gp but me on antihistamines but they didn't help. I have asked to see allergies team who have said its definitely not an alergy. She thinks maybe kidneys and is running a full thyroid panel ( I think the rheumatologist did but she said she test for more things). Today I woke up on my back, bot hands and wrists totally numb again. I have sleep apnea, I just under pre diabetic. Any thoughts as it if the alergy clinic comes back OK I want to go private. My hba1c?? Was 41. I asked the gp to give me my overdue pre diabetes blood twst form yo do alongside the thyroid and kidneys - no reply
