Hello,
I'm sorry to hear that you're currently experiencing so much pain. Providing you've given your injury ample time to heal (it varies from person to person depending on immune function), but I'd say, with a healthy mind and body, 2 months sounds sensible.
I think when we develop various symptoms ranging in severity and listen to numerous individuals, it causes our fear, anxiety and worry to spiral out of control. The hardest part and most rewarding is to change ones thinking and the association we have with fear etc. I've noticed all of the questions you have posed are coming from a place of uncertainty, doubt and fear, on the plus side...
There are numerous techniques that you could deploy when you are feeling certain sensations within your mind-body.
These include;
1. Self talk, making a gentle enquiry to your inner child with love and compassion and establish why you are feeling the way you are.
2. Free writing - trying to explore a connection and understand any limiting beliefs that you may hold.
3. Practice meditation and mindfulness - being more consiously aware of your emotions, the more you do this the less a hold emotions such as anger, fear and worry will have on you. It will also help activate your relaxation response.

4. Learning to shift your focuse from the body to something neutral, the outdoors, the sunshine etc.
5. Take up yoga and practice an exercise that embodies movement and breathing. I've found this particularly beneficial for my own journey.
6.
EFT - emotional freedom technique, there are numerous threads on the topic and it's also worth looking into.
7. Practice outcome independence...

There are countless others methods and you'll really have to explore the Wiki.
You'll find these techniques only give a certain amount of return, so if you are finding they are not benefiting you, try another. Our journies are all quite different and unfortunately, there isn't one modality that suits all.
I hope this short list will provide you with some options that you can build into your regular practice.
All the best and wishing you a healthy mind and body.
