Re: cant smell or taste :(
Unfortunately, you probably need to head back to the ENT for a follow up visit about this particular issue. It's possible that there is still enough inflammation in your sinuses to block the receptors that capture smell and addressing the inflammation will solve that problem. It's also possible that your previous surgery damaged the receptors - which is a very common problem - and that you won't regain your sense of taste/smell.
I wish I had something more encouraging to tell you, but either way, you really need to see an ENT to try to sort this out.
