I will get to all the questions, including the one about height dysphoria.
Blood thinner: Dr. Assayag did prescribe Xarelto for 30 days after surgery (I think). I ended up not taking it because I was already taking a lot of blood-thinning supplements and herbs, like cod liver oil, and I was going to the sauna a couple times a week, using a calf massager and heat pads, and generally moving my legs throughout the day (but without any weight bearing). Note, I didn't tell Dr. Assayag this and he didn't sign off on it. You should follow your doctor's instructions and take the medication as prescribed. I'm not a very good patient I guess
PT: I did PT sessions every two weeks at Sinai Hospital whenever I would go there for X-rays. Those sessions were quite painful and, to be honest, I didn't feel like they were particularly helpful because the stretching effect would quickly dissipate. I also did daily sessions with my dad, who was staying with me, for 15 to 20 minutes once a day. This was a lot less than recommended but I never had the motivation to increase the intensity because when I would go to PT they would say that my flexibility was fine relative to the stage of lengthening that I was at. I wasn't trying to circumvent the traditional protocol, but things just ended up that way because I wasn't able to find a local PT who was familiar with the leg lengthening process. I can talk more about this if it's interesting.
Now that I can weight bear as tolerated, I've been doing PT twice a week locally. The PT is focused only on muscle strengthening as my flexibility is pretty normal. I feel like those sessions are helpful because they force me to do squats, lunges, etc., but if you're a disciplined person and can commit to doing those exercises by yourself, the formal PT sessions aren't strictly necessary at this point. My insurance is covering them, though, and the copay is only $9 per visit, so I think it's worth it.
Bone healing: I was full weight bearing two weeks after I stopped lengthening, on both legs. My bone healing was indeed faster than usual. This was probably due to various factors: 1) I was eating a big calorie surplus, including high-calorie Ensure, and I never lost weight after the surgery (in fact I gained weight). This was a good strategy as I quickly lost the extra body fat once I started walking again; 2) I didn't use opioids or NSAIDs, at least not consistently, just Tylenol; 3) I took a lot of supplements that have research supporting their use for bone formation, like Bone Up and cissus quadrangularis; 4) I went to the sauna and used heating pads throughout, which theoretically enhance angiogenesis and bone healing; 5) I lengthened the tibia at 0.5 mm/day and the femur at 0.75 mm/day for the first half and 0.5 mm/day for the second half of the process.
Nerve symptoms: I didn't have any nerve symptoms on my left leg. On my right leg, I opted not to do a prophylactic peroneal nerve decompression (as I'm a stubborn patient), and I ended up getting partial numbness on the outside of my leg and top of the foot. Those symptoms have improved considerably since I stopped lengthening. I think I've regained full sensation in about half of the previously numb area, and the areas that are still partially numb are probably 60 to 70% recovered. It hasn't even been two months since I've stopped lengthening the right leg, so I do think my nerve will make a full recovery. Even if it doesn't, the partial numbness isn't bothersome.
I didn't get nerve pain, maybe only a little bit, but this reminds me: Dr. Assayag prescribed gabapentin for the restless legs syndrome that I had in the first few weeks after surgery. I took it for three weeks, but I feel like it didn't help at all for that symptom, and it was difficult to taper off of. If you look on Reddit, a lot of people say that gabapentin withdrawal is worse than opioid and maybe even benzodiazepine withdrawal. So, if you get nerve pain, my advice is to first slow down lengthening and/or take a few days off, rather than go on gabapentin. For restless legs syndrome, I found
quinine to be super helpful. I think its use is discouraged in the US for some reason, but it worked really well for me. And I think time and healing will take care of RLS in any case, so you shouldn't feel panicked if you experience it.
Regrets: I definitely don't regret doing this--I think it's one of the best decisions/investments I've ever made, only second to corrective jaw surgery. It cost me about $90,000, which is relatively cheap, and I was able to get paid medical leave at work. I regret the fact that I spent a lot of mental energy being anxious during the process, browsing this forum, and waiting for things to get really bad, which they never did. But it's easy for me to think that way now that I'm close to the end and everything went well.
