Hi Goodbobby,
One reason the consultant may have given you that suggestion not to go down the route of immunotheropy is the cost, as you say you went to him privately the cost may have fallen onto you or your private medical insurance supplier, as far as i am aware the cost for the 3years runs to about £13k which is a massive amount.
Now as far as i am aware the NHS would not waste this sort of money on something that does not work. But also the consultant i have been seeing has stated that the effectiveness is 93%+, it takes a total of 3 years to go through the whole course. starting weekly for 12weeks(or more if you react badly or have to take a week off, in my case now 14weeks) as they build up to a total of 2 stings, then monthly for a year, continuing through the winter so no loss of effectiveness, then finally every 6weeks until the end.
If they find you are still reacting at the 2sting level badly they can then increase you upto double that, but that has to be done very carefully for obvious reasons.
I have found that depending on where you are depends on what advice you get and not all of it is good. My consultant did not even consider asking me to give up as he has said he sees lots of beeks and they are always very pragmatic about the stings and as long as you are careful (which you seem to be) the risks can be reduced.
I wouldnt bother going back to the guy privately, but i would really urge you to go back to your GP and demand the course of treatment, he has to give you a referral even if he dont want to. I would say it really takes strong will to go through it, it isnt easy but I feel at the end i will be much better off having been thro it.
For you you would probly end up going upto london for yours or down to brighton as its not done in most hospitals. But go for it dont take the docs word, it really is worth it.
I hope this makes sense.
