I'd like someone to tell me everything will be ok please 
My dad has complained of chest pains, shortness of breath etc for a couple of weeks. Gp said it was muscular (didn't do an ecg, which I was surprised about, but I'm not a medical professional...)
Yesterday his leg started to swell and he was getting severe pain in his side. He went to a&e, they kept him in, did an ultrasound today which showed a blood clot in his groin and is now waiting for a CT scan to see if he also has one in his lung (seems likely). He's quite short of breath and in pain, has had pain relief but it's not touched it.
I can't understand it as he's fairly active, hasn't flown for a good month or so, doesn't smoke, no family history and is already on blood thinners after a mini stroke earlier this year.
I'm hoping that they'll give him blood thinning injections and that will sort it, but what happens if they don't? Not sure I can cope with the alternative...
