Hello CSue. Thank you so much for posting your interestng problems and I hope you get lots of replies. Unfortunately, many people who have reversals which are successful, no longer have a need for the support of a site like this one and only pop in from time to time to see what's going on.
Three months is really no time at all in the healing process for these types of operations and many of the weird pains and sensations will be due to that healing process. However, the advice must be that if you feel worried about it, whatever 'it' is, then you should dseek professional advice, if only to put your mind at rest. That would be the number one priority because if there is something physically wrong, no amount of 'thinking' about it will put it right.
When you talk about PTSD and paranoia, these are things where I do have some small experience so I will try to make some helpful comments.
Firstly, I have absolutely no doubt that the acute trauma of having these sorts of conditions, going through the operations and having all the associated worry and stress can, and does, cause the condition that has become known as Post Traumatic Stress Disorder. Personally I would say that some can also suffer with 'pre- traumatic stress' as well but that's a different story. The 'Disorder' element is when the condition goes beyond a very hazy line between what is expected before the person gets better, resulting in a need for outside intervention to bring the person back to what could loosely be called 'normality'.
In all my years of working with people who have been labelled as 'paranoid'. Once the background is fully understood, I have yet to come across anyone who has not had good reason to have some degree of paranoia. --As the saying goes "Just because you're paranoid, it doesn't mean they are not out to get you!" The term paranoia is usually used in psychiatric and psychological circles to describe those who allow their emotions and sensitivities to develop to the extent that they get out of hand and adversely affect their daily lives. There are a miriad of different ways that people adopt to control and manage their sensitivities and emotions from yoga, exercise/sport,hobbies, sex, concentration, education, distraction, self-harm,and many others. I use writing poetry or prose to achieve an equilibrium when things affect me too much that I need to distance myself from the source of the problem.
As with so many things in life, there is no single answer to this problem that suits everybody. We each need to figure out what distracts us best and helps us to move on and leave the crap behind. I happen to be a firm believer in 'Self- Organised' living and reflecting, so I rarely seek help from others. However, I have met many, many people who cannot learn by themselves, of their own volition and need someone else by their side as they find solutions to whatever problems life throws at them. If you are such a person, there is no disgrace in recognising this need because recognition is one of the first steps to putting things right.
The only thing I would say about that approach, is that you need to be very careful who you put your trust in to help you in times of need. There are lots of people out there,(some of them with impressive qualifications) who are on the look out for vulnerable people so that they can relieve them of their money, without really helping them with the underlying problem. These despicable people will often cause more trauma than they purport to be helping with.
One technique that I have used that proved to be very helpful with certain people, was to get them to keep a diary of what they were worried about. This enabled us to work out the percentage of times that the focus of worry either happened or did not happen in reality. I used to point out that the level of 'significance' is usually set at 5%. Anything under that, could and should be used as an indicator that whatever they were worrying about was most unlikely to happen. This approach is a bit like weather forcasting, in that it helps to give people confidence in thinking that rthey are worrying unnecessarily. However, it doesn't necessarily stop it raining unpredictably!
Perhaps I've said enough. I hope you find your way of managing these thougths and emotions sot hat you control them, rather than let them control you.
Best wishes
Bill
