Catra,
Im sorry of how things are going on but be positive and try to relax for your well being and your sweat little girl.
The dr will for sure do the what they can to treat your pregnancy and rsd the best way possible and care, is hard when we have all the worse case scenarios at once but there is always a light.
Try not to worry so much, If the test is not showing good results ,keep in mind ,many pregnancy woman suffer from stationary diabetics and will go after the pregnancy ,hope is not the case but there is a way to treat it an for you and the baby be well.
A c-section will also be if need to happens supervise by the rsd specialist and your ob/gyn and they together will,provide with the best care to prevent spreading and pain control pain , remember also our part is to let the dr know we can't be on pain,insist and educate them if necessary but don't lose hope,keep,the faith,you both will be fine.
Having pain control after any surgery is essential ,make sure you have medications for pain,also,if you planning to breast feeding ,keep in mind ,many drugs can be harmful for the baby ,consider the possibility at the first weeks nit to do it if you need to be in pain meds which I'm sure you will need if a c- section is require , you might nit be in the case but I just mentioned to prevent pain,always prevent pain after the surgery.i know this is not the same as having a baby,but after I had my gallbladder surgery,I was thinking I will to need pain killers and only my tramadol will do the job,but no ,my dr and anesthesiologist took good care of me avoiding pain,and when a woke up,I was in the first time feeling pain for real and realized ,tramadol won't do anything ,I called the dr right away and asked him for something else which he did ,he gave me Tylenol 3 for two weeks and it was a bless, I didn't have pain at all,considering I had two surgeries one after the other,I had my scs repositioning on my abdomen and the gallbladder like a Month apart but preventing the pain was the best thing that I ever had,I feel occasional pain in my scars but is not like rsd spreading , my rsd was spreading a year early and my dr didn't took care,the dr who saw me didn't know rsd but listen to me and helped me ,talk to the dr and sure they will help you ,my frustration made me believe and felt like he didn't care but I was wrong,I was in pain and did nit see the dr good intentions to understand me and help me ,but he did and I'm so thankful .
Hope you get a good care,I know is not same comparing my gallbladder surgery with your beautiful pregnancy ,it was my way to tell you,pain after any surgery needs to be prevent . Both of you will be fine , please try to be calm,rest ,relax and focus your energy in be well and you will be.
Gentle hugs and lost of love ,Jesika .
