Do antibiotics make you sore?

I'm a runner. I go on and on on this site about running. It's such a part of my life.

Well, Mondays are normally long run days. I have energy pent up from the weekend and I can breeze through 8, 9, 10 miles and feel great.

Today - BOOOOOOOOM was I sore! I ran but I felt like I was dying and that almost never happens. I started a course of antibiotics on Friday and while my run was good on Saturday, it was only a 5 miler and Sunday is my day off. So is there anything relating exercise to antibiotics?

I run on an incline ever since the half marathon, but it hasn't bothered me until today.

First things first what antibiotic are you taking?  Different ones react differently with your body.  If you feel uncomfortable telling us try asking your doctor

Well, the penicillin family can have body and muscle aches as a side-effect usually with chills -- basically flu-like symptoms. If that's the case, then you need to see/call your doctor again first thing.

If you've been on them since Friday, it seems a bit unusual that the symptoms have taken three days to develop (usually it would have been noticeable in those first 24 hours or so) -- but it's not impossible.

Man, it's just one thing after another for you these days! Anyhow, call your doctor tomorrow. Best wishes.

I think it's Doxycycline... but it was given to me to treat the breast lump that I posted about last week!:-)

If it is indeed Doxycycline two of the side effects are feeling tired and joint pain.  I would call your doctor and check bases with him just to make sure.   Give him detailed info.  How much you run your streching routine(i hope you do strech), what your warmup is(you do equivalent to a half mile warm up right?)  that sort of thing.
