Is it normal after you have a Atrial flutter ablation procedure is it

It depends on what you're doing and how soon after the ablation. Depends on what the electrophysiologist did, and how irritated your myocardium is. For several days after an ablation, the scarification process continues, meaning the lesions continue to 'grow' a bit, but also to heal over with fibrotic material...which is impervious to the unwanted electrical impulses that cause arrhythmias. So, most people find that their HR is elevated by between 10-30 beats per minute. If yours is 120, and you're walking, especially in the first six-ten days post-procedure, you're doing well.
On the other hand, if you are sedentary, at the table, watching TV, reading, at the computer (and not on the news), and your HR is north of 100, there's a good chance something is going on. It should be investigated, either yourself with your resources, with a Kardia Mobile, or with a Holter monitor, but if that rate persists more than 24 hours, then more urgent care is needed and you should go to a local ER.

When was your ablation? Had gone back into aflutter? Get a Kardia if you do not already have one. Are you overweight. Are you unable to do things that you did before your ablation?
Aflutter ablations are relatively very high success rate in the high 90s. But the trauma to your heart will have it inflamed and if you are doing this the first couple of weeks after the ablation. I'd say you are pushing it a bit. What does you doc say?

I understand 100 is high and above is not normal but what do you do about it because the doctors don’t tell you anything even though you discuss it with them what is the next step?

What I would do is to press them for a plan. If they shrug and say 'Live with it...many do, ' I would consider that unhelpful because clearly I am asking for solutions, options, contingencies....ANYTHING but a shrug and the advice to get on with my life, or to make preparations for an untimely death.

You can live for a long time with an arrythmia, most of them, but nobody asked will say it's real living. In fact, it can be so awful that one begins to go downhill. So, one should seek a remedy, and if it isn't forthcoming from one cardiologist or EP, find another who will help...somehow. At some point, it may indeed be the case that there's nothing left, but there is almost one option worth a try rather than to face a slow dying on the vine.
