Timber and Erin,
So sorry ladies that you are going through this. Timber, your case sounds pretty bad.
I don't usually share my story on the board, because I don't want to "freak" anyone out since I had such a rare and unusual case, but I think that I can speak to some of your issues and please feel free to PM me with any questions--no matter how "personal"!
I was 41 when I first did IVF. I was completely naive and had no idea really what was happening. Such a complete change to how I am now--much more of an active patient and highly involved with decisions.
Anyway, due to my age, my RE was aggressive with treatment, which was fine with me. I took high doses of meds and responded well--although too well. I started being bloated before retrieval, but like you I minimized and didn't realize exactly what the risks were. By retrieval I was feeling very bad, but was told not to worry by doctor. They retrieved 28 eggs, 24 which were mature. I wish my doctor had been like yours and suggested FET. I would STRONGLY recommend any woman give the option of potential OHSS versus freezing and waiting--wait.
A few days after transfer I couldn't sleep unless propped up and had gained several pounds. Anyway, long story short I ended up in and out of the hospital for about 7 weeks total. I had 3 parecentisis--draining from the chest cavity and 3 thoracentisis-draining from the stomach. I was only given a local at incision site, and can tell you for one of the perencentis I felt it and it hurt worse than anything I could imagine. I never heard of transvaginal draining nor the type of anesthesia you had.
For anyone undergoing either of those draining procedures, I would definitely encourage they get good pain meds--although I never had "transvaginal" so I can't speak to that.
Erin--gaining 8 lbs in 7 days doesn't sound good. Although you hate needles, I would recommend you go in again for a check before it gets too worse. If they catch it early you can have the draining done outpatient and not miss as much work.
The fluids also threw off my electrolytes, which is why I was in the hospital a lot...I was needing lots of IV fluids and Mg, etc. My heart rate was arrhythmic and my doctor was worried that I could have a had a heart attack! I was very uncomfortable as well. In addition, I had lots of other secondary issues, and I was a very healthy person before all this happened. I was not used to being "sick" and found it really hard to stay in a hospital. I went to the gym several times a week, never really sick....and then this hit.
Then, to add insult to injury, it turns out my pregnancy was ectopic. After all of that I wasn't going to get a baby afterall. I was so devastated. We proceded with a shot of Methyltrexate, but I got dreadfully sick from that and ended up back in the hospital with a life-threatening case of CDiff. I was on very aggressive treatment for that and when finally discharged, my tube ruptured the same day! I was back in the hospital for emergency surgery to remove my tube, part of my ovary and my appendix. (We had two embryos growing turns out--one on my tube and one on my ovary. With IVF, I don't understand how that happened, but it did.)
It was quite an ordeal to say the least. And, very unusual---my doctor said in his 12 years of practice he had never seen a case of OHSS as severe as mine, and never one that cascaded so horribly as mine did. I was out of work a total of 3 months (lost all my vacation/sick time that I was planning to use for maternity leave.

)
Since then, my treatments have been much more cautious and I am much more alert to any symptoms of OHSS. Although most cases aren't as severe as mine was, from what I hear from others, even moderate cases can be quite disruptive and uncomfortable.
My advice to anyone concerned about OHSS: Drink your Gatorade, rest, and report ALL symptoms to your RE. Better to be overly cautious then to let something progress. OHSS can progress quite rapidly.
And, if anyone has the opportunity to avail themselves of postponing transfer to avoid even the risk of OHSS then I would suggest it. Although my RE assured me that there were no risks to the pregnancy as a result of the OHSS, I have since found research to suggest the contrary.

Best of luck to you ladies. Please take very good care of yourselves and report every symptom. I am sending you positive energy and well wishes.
