"Botox clinic in Neurology"

I suffer from semi facial spasm, and after finding out that this was caused by a twisted blood vessel touching on a nerve in the centre of my brain, I was told by the Consultant at QE Birmingham that it was inoperable and I was referred for Botox injections every three months. Over the past three years this clinic has been hit and miss, due it seems to the fact that the Doctor who gives the injections retired in 2015 and returns only for these botox clinics. As the Doctor spends time out of the country it appears that the hospital have to negotiate with them as to when they can perform a clinic. This is very frustrating as I can just about last the three months without spasm, but after that time the spasm in the left side of my face is uncontrollable. I have no issues with the Doctor or the nursing staff, they are very professional, but when the dates keep changing if I am away on holiday I can go months without the injections. Added to this the fact that twice I have not received appointment letters, only finding out by ringing appointments myself, the situation is unsatisfactory. My last clinic was August and I expected a clinic this November but this has not happened. I contacted Neurology today to be told that they did not know when the next clinic will be as 'Management are talking to the doctor to agree a further clinic'. I was told that there is no one else in Neurology that can give botox injections as it is a specialism - what an insult to my intelligence. I was told that the Doctor does still do private practice at a local Private hospital and of course I would have to pay for that, or I could be referred by my doctor to the Botox clinic at the Queen Elizabeth in Birmingham. I am retired and do not see why I should have to choose one of these alternatives. Is the Manor Hospital a 'mickey mouse' operation or does it consider itself a cutting edge establishment. Surely when someone has been retired for two years they should cease relying on this person and organise someone else to ensure that these botox clinics run every three months. Giving Botox injections is not that much of a specialism for a medical professional (research it) so please do not fob people off with feeble excuses.
