I have been experiencing some strange symptoms on & off for about 5 months.It started with me coming up in random patches of hives round the time of my period.G.P gave me anti-hystemines which helped but my skin would still come up bright red if i scratched the surface for some time. 2 months ago had palpitations on & off for 10 days. happened again last month but not so bad.2 weeks ago a bad chest pain in the evening for about 2 hours. 2 days later same thing happened but next morning my bottom lip swelled up like id been punched.went down in a couple of hours. Been fine up until last night when got bad chest pains again lasting about an hour. This morning after breakfast my lips swelled up & stayed like that for about 5 hours.
I have had an ecg done by gp & had cholestoral checked all came back good.I am 41 & usually in good health.What is going on???
