Since I suffered Anaphylactic Shock, my veins are flabitic and my head and throat are sore and larger than before. Will this return to normal in time or will I stay like this? I used to sing and now my voice is different and I can't sing. When I eat, the food is difficult to swallow since the attack. The flabitic veins really make me think because I have always been so healthy and now I've been ill since then and I was just diagnosed with Congestive Heart Failure. My legs are swollen to double normal size even while I'm taking Lasix. I think it's the closed veins.
