Glad you are not really poorly then, just spasmodic! join the club - Tamsyn has been in hospital with what was initally a suspected collapsed lung, then a suspected pulmonary embolism, heart attack........ and finally diagnosed as costochondritis, a post-viral (she had a cold 2 weeks ago) inflammation of the cartilage around the sternum, where the ribs join to it. The pain from this made her intercostal muscles go into spasm, causing her to have symptoms similar to a heart attack. Pretty scary for her, but she is popping pain killers and almost back to normal!
If you keel over mid-song, do you want me to keep it going til you wake up?
Seriously though glad its not all the things it could have been which no doubt all passed through your mind while you werer waiting for answers!
Cheers, Lucy
