I am getting so frustrated because I feel that I can't do any exercise. Like others, walking on the flat is usually OK, inclines however are not possible. I have developed both postural hypotension and postural vertigo now which, again makes it difficult to walk even. The nausea is bad with the vertigo despite medication and I just feel like - well - crap unless I am sat or lay still. I will be seeing the doctor again on Tuesday who is testing my blood for all sorts including inflammation which could be present after my gall bladder removal in July. I feel as though I have got loads wrong with me and feel also as though I am getting weaker as I can't exercise. I have permanent AF and heart flutter - due for my 2nd ablation, waiting for date. Rant over, but seriously, and ideas?
