Well my INR range is 3-4.5 and the last couple of days felt tired etc checked myself and it is 3.2 but have an appt in Haem tomorrow, but noticed my hearing was muffled, as though one has climbed to a high altitude and then it is waiting to be popped. I feel good at 3.5. I feel so cold and living here in SW it is cold and today when we went out I just did not want to get out the car, mind you my husband said he was chilly too, so must have been cold!!! I do sometimes suffer from Tinnititus but this is a muffled feeling. I could go to bed now but I don't like going when my daughter is doing her A level revision, but will probably drop off as usual. Does anyone else suffer from this feeling?
