Prayer is always welcome

So, for the last few weeks I have had some pretty bad back pain. For no known reason. I went to the doctor and they didn't know what was wrong. I can't sit in class because it hurts too much and sometimes it is too much to get out of bed. The doctor gave me muscle relaxants which help me sleep at least but they make me so groggy and out of it. I hate it. I am taking tons of ibuprofen which is also not helping. Did I mention I also have a sinus infection which comes with a headache that refuses to go away? Basically, I am feeling miserable, I am missing a lot of class, and there is no end or solution in sight. Please pray for me. I am tired of this.
