So for the past 2 weeks or so, I have had some mild, throbbing pain in my body - specifically my groin, my chest, my clavicles, the back of my neck, my lower back, and my head. It usually goes away after 5-20 minutes, sometimes longer. I just moved into a new appartment with my girlfriend three weeks ago, and had to carry a lot of heavy packages, so I might have pulled something, but I am not sure.
Also, starting about 2 weeks ago, I now get nauseous whenever I take the tram or train, or travel in a car, though this never used to happen. Further, in the past week I've often become nauseous and gotten headaches when exposed to direct sunlight for too long. I used to have this problem as a small child (until I was about 10), but since then it hasn't been a problem, until now.
Finally, for the past 2 months or so, I have occasionally (maybe 1-2 times a week) started coughing for no apparent reason, though it is almost always mild, except this one time when I woke up coughing in the middle of the night.
I have a history of anxiety and hypochondria, though the anxiety isn't really present at this time in my life. Obviously, given all the symptoms, I am worried about my health. Does this sound like anything suspicious? What might it all be? My crazy mind is telling me that I have progressed into advanced stages of cancer without even knowing it, though my left brain is telling me that's highly unlikely. I have an appointment with my GP, but the last time I met her for eczema, coughing and aching, she said to take things one at a time and focused on the eczema on my hands (turns out it was probably caused by dry skin), and I am worried it will take several appointments to get through all the symptoms. Is there a specific direction I should be looking in?
