I don't know what to do

I saw my neuro Wednesday. I had another baseline EEG and a 48hr EEG done the week before. They lost one of my memory cards for my 48hr EEG so they only had 24hrs of info. Everything came back as normal. I am really upset about them losing my memory card, they lost the card that I was having symptoms on. I also had problems during my baseline and my neuro said she was going to go back over that too. During the baseline the room started spinning like I was on an amusement park ride. I told the tech, and he asked me if I was going to get sick and I was unable to answer him, he continued to ask me a few more questions but I couldn't answer. I am so confused now though, I thought for sure we would have an answer since I had something happen during the test. I also have been having strange/severe pain around my left rib cage so she examined me and found some lumps on that side. She ordered a chest x-ray and abdominal ultrasound. I went in Friday morning for those, during the ultrasound they only looked at my spleen and my left kidney. The ultrasound tech left the room and then took me for my chest x-ray, and there they only did a front view and my left side again. This is what I don't know to do about... My neuro and I talked about medication I was on Topamax 75mgs twice a day. She had upped me to that the month before and I was not doing well on that dosage so I told her that I didn't like it. So she told me to go back down to 50mgs twice a day and to add Keppra 500mgs at night. Now what I don't understand is why am I adding another seizure medication if all my tests are coming back normal??? The Topamax is working, I have not had a t/c since starting it, so why add Keppra?? I don't like the possible side effects, really thinking I should see what these lumps are before starting something new???? What do you think??? Thanks!!
