PATIENTS of Dr Michael Watt held a rally at the Royal Victoria Hospital in Belfast yesterday to show their support for the consultant neurologist.
Supporters have also set up a petition calling for Dr Watt to be re-instated and for the Belfast health trust to "give us the answers we need".
They say they are being "stone-walled" and forced to see other consultants - which is impacting negatively on their health.
More than 2,500 of Dr Watt's patients have been recalled following a case review by the Belfast Health and Social Care Trust.
The recall comes amid concerns some patients may have been misdiagnosed.
While some patients have spoken publicly about concerns around his care, others have praised him for transforming their lives.
More than 400 people have so far signed the petition with comments describing Dr Watt as "kind", "professional" and "genuinely caring".
One of the patients responsible for organising the rally and petition is Rhonda O’Neill (44), from Magherafelt.
She suffers from a rare neurological condition - autonomic neuropathy - which results in her organs not working properly.
She said she has been "more traumatised" by the removal of the consultant than by all the health problems and surgery she has had to face over the past eight years.
"I have been struggling on myself since Dr Watt left. Nobody knows what to do with me. I have another neurologist now but I have been told I will have to go to London because they don't have anyone here who knows enough about my condition.
"There were treatments Dr Watt was giving me to slow the progression of the disease but since last June I have had no access to these."
Christine Lynch (55), joint organiser, was diagnosed with multiple sclerosis by Dr Watt in 2005.
She said: "He is absolutely outstanding. He put me on a drug which has stabilised my condition.
"I don't want another consultant. I am waiting for him to return. I have complete faith in him."
Other supporters included doctors and nurses as well as passing motorists who sounded their horns.
The petition will be sent to Dr Cathy Jack , the medical director of the Belfast trust and the General Medical Council.
In a statement the Belfast trust said: “We do recognise this is a very difficult situation for everyone involved; for all of Dr Watt’s patient’s and for everyone who knows him.”
