I have been feeling especially weak tired and fatigued the past two weeks. So much to the point of not being able to ride my bike or go on walks more than 20 minutes long. If I do I feel like I'm going to pass out. I've also been getting upper back, chest and jaw pain. Lots of breathlessness. Finding it very hard to cope with day to day activities. Mainly due to the weakness and feeling faint. Also I've been more dizzy than usual. Today I went on a 20 minute walk and halfway through I suddenly started to gag - after a few minutes I was vomiting everywhere - I was rushing home and vomited about 6 more times on the way. I was feeling very hot and dizzy. Now a few hours later I'm laying on the couch and my chest hurts, my stomach really hurts, and I feel generally weak and unwell. I am very worried as I've looked up my symptoms and heart failure keeps coming up. I have thought "something must be wrong with my heart" in the past few weeks anyway due to the weakness and tiredness but after searching my symptoms I am sure. And very worried.
Has anyone had any similar experiences? Any help would be appreciated I am close to just going to A&E although I know they won't take me seriously
