I ve been in and out of my doctor s office all summer with a variety of complaints. Back pain, numbness/pressure in my thigh and then shoulder. upset stomach/queasiness, cramping. I ve had a lower back x-ray which was negative. Some blood tests to evaluate my thyroid and my doctor said to just see if anything looked off, all ok. And I was tested for a UTI. I m now in physical therapy, ostensibly to treat the back pain. And I have Xanax to take for sleeplessness and anxiety at night. I m willing to believe that I am anxious--but I really think it s because I don t feel well and I don t know what s wrong with me. I m a 27 year old female, generally very healthy, I eat well and exercise regularly (teach aerobics). And I d just like to feel better. As of late, I think I m having night sweats and I wake up throughout the night. The back pain is also now in my upper back and I have pressure, feeling of pushing on my ribs most of the time. Also, my normal temperature is around 96. I don t want to continue to haunt my dr s office, but should I be concerned?
