Fatigue and Chest Pain

6 months since diagnosis...

4 months since surgery...

6 weeks since last radiation treatment...

4 weeks since starting Tamoxifen...

2.5 weeks back at work...

Towards the end of my medical leave I was starting to feel better and things were looking up.  Then I started working again and things took an abrupt turn for the worst.  If I had any fatigue when I wasn't working, it wasn't noticeable.  Since starting work though, I became much more fatigued.  Is it possible to be this tired from 8 hours at a desk job?  I can barely get through my work day and by the time I'm done I don't have energy for much else.  On the weekends after my long morning walks, I end up in bed for a few hours - too tired to do anything else.  There was at least one day where I had to take the day off of work.  There were many more days I wished I could rest.  

The fatigue was one thing, but I also started developing chest pains on the cancer side. This wasn't coming from the surgical sites.  It felt more muscular, in the chest wall.  It was isolated to the upper left quadrant of the right breast - not too far from the heart.  The pain was a dull ache that felt like pressure on my chest on one side.  It started about a month ago but it was mild then.  Now it is getting very uncomfortable and worrisome.  I reached out to all of my doctors.

The surgeon thought it was inflammation from the radiation.

Oncology suggested getting an EKG and going off of Tamoxifen for couple of weeks to see if it helps with the fatigue.

Radiation oncology didn't think it was radiation related.  Told me to take anti-inflammatories and rest more.

The PCP wants to let my cancer team handle this since it's probably related to the treatments.

I decided to take oncology's advice and stopped Tamoxifen yesterday.  Then I went to a walk-in facility and got an EKG, Tropnin (heart enzyme) test, and chest x-rays.  All were normal so thankfully it was not a heart issue.  It was getting to a point where I needed to have some relief, so I popped a few ibuprofens.  After some time, I started to feel better.  I was also sleeping pretty well until a smoke alarm started beeping due to low battery.  I had to get up and rip the alarm off the ceiling and pull the batteries out so it would shut up.  Then I couldn't get back to sleep.  But I digress.

Anyway, I will be popping ibuprofen for a while and cut back on my exercises.  On the 21st I have a CT scan so hopefully I'll have a better idea of what is going on then.  If I'm lucky I'll feel better by then, but it seems inflammation can take weeks or months to heal.  I really don't think I can go on like this for months.
