This might be some tough love for you. From what I’m reading, it’s like your anxiety is doing the typing.
If you can get an erection where your glans is even harder than before (to answer your question: probably from healing and the amount of time you have not touched yourself), there should not be anything wrong with your member. If you believe what firegoat said to be true, let’s do some math then. If your glans is deflated because you are healing from the tears you had, then rest is really the thing that works. And it did because after 24 hours not touching you had the hardest in a while. Then the next thing you overdone it by a 2 hour session which probably has set back the healing again. So I’m happy you are on the right track committing to a week of no touching. Imagine 2 weeks no touching. We know now that your glans is not broken.
Let’s try to reduce your anxiety a bit more. In fact, I think that you are starting to like your anxiety. Yes, a wild claim but it seems you are getting some sort of juice out of looking up ‘your problem’. Anxiety is no joke but I hope you realize that it’s mostly in you head and are able to recognize this compulsion and let it go. Assume it’s fixed now, you have had the proof in your hand(or hands depending on your size) for 2 hours. Furthermore, you probably should start going out of the house again to combat your anxiety. I suggest going to the gym and doing some leg exercises. After a few sessions you will be surprised how hard your glans is! I have also experienced that fasting sometimes improves hardness, you can experiment with fasting and see what works for you. It can become a great tool in your arsenal.
To add, I think the doctor you called is trying to get a new patient by scare-tactics. I think this because the call was so rushed, nothing is free. In my opinion, you can remove venous leak from your mind.
Let’s hear about your week of no-touching!
