Hello  Ana1994 and thanks for posting, 

I am sorry to learn that your dad has been having these symptoms and is having tests to find out why. I appreciate that 'not knowing' can be unsettling. 

With any set of symptoms, there are usually a number of possible explanations, doctors often want to do tests more to rule things out and narrow down the possibilities. 

I  understand you asking about other people's symptoms but they might not have much bearing on whatever is going on with your dad. 

I do hope you find out more soon. 

If you want to talk anything over, please do give us a call on Freephone 0808 800 4040, we are here from 9am till 5pm Monday to Friday

Best wishes, 

Julia
