Suggest Treatment For Sweating,itchy Skin And Bloating

Hello. I hope you can help me. I m a 50 yr old female. I ve been having symptoms for at least three yrs with no diagnosis. I will list my symptoms Severe generalized fluid retention. I have pitting edema every where on my body. I take lasix for that. I m having profuse sweating with or without activity. I feel extremely hot all the time. I have dry itchy skin I eat very little yet I am gaining weight in my torso. Sometime it also becomes so bloated with fluid my skin stretches and it s very uncomfortable I feel very tired a lot of the time. I run out of energy quickly Sometimes I m so weak,my body feels like it s made of lead When I become bloated, my husband notices that I talk very slowly and my thinking process is slow. These symptoms are ruining my life. I ve seen an OB/GYN and was put on HRT but it made things worse. My GP doctor ran the usual test for the fluid retention, all was negative so I was put on lasix but the edema is getting worse and occurs more frequently. .....thank you, Lyn
