Hi Chris,
I remember the feeling of not being able to let anything touch my skin, even loose clothing would seem to irritate it. After the first or the second expansion this seemed to settle a little. There is no need to wear a bra at this stage i did not start to wear a bra until after i had my silicone implants inserted.
The spasms do settle. I only have them now when i am really cold. The expanders are not the most comfortable experience but as soon as the silicone implants are in its a much more natuural feel and look.
I did not have a heamatoma ( wrong spelling) but i did get a very bad infection and had to have one expander out for 6 months so i can understand how nervous you would be that everything runs smoothly from here on.
I really hope that you are ok, i wish you all the best for your first expansion.
