Odd one this. I've noticed (after 3 years - doh!) that my headaches (could be migraines as that what the GP has been treating me for) happen the day after a bike ride - even just the 30 min commute to and from work.
I only realised this when I'd been virtually headache free over winter (when the bike stayed in the garage), and for 5 weeks in the spring when convalescing from a bike crash.
I ride a hybrid flat bar and notice I get a hell of a lot of tension in the muscles between my shoulder blades and in the muscles between my neck and shoulders, and the headaches could be differed pain from this.
I know that back pain can go with cycling, but didn't realise headaches did, any body else have similar symptoms...?
Could well be tension headache. Dehydration headaches (which are physiologically similar to a migraine FWIW) are a possibility but on a 30 minute commute that shouldn't be a problem, unless you're routinely not drinking enough and that ride pushes you over the edge. Onset of a dehydration headache is normally within a few hours, but could be the following morning if you go to bed dry.
Going with the tension headache theory, I'm not a fan of physiotherapy treatments like TENS or ultrasound stimulation (no evidence for any results other than symptomatic relief and emptying your wallet), but getting some advice on strengthening exercises and stretches (and doing them yourself at home) could be helpful.
Varying your position during a ride could also help. A lot of people are pushed towards flat bars for a "more comfortable, upright position", but IMO you can set drop bars up to give the same position on the flats, plus a choice of other positions (hoods, drops) for variety.
Try this experiment: hold your arms out as if you are gripping your flat bars - palms to the floor, elbows rotated outwards. Now rotate your palms to face each other, elbows in a bit like you're on the hoods, or outer bend of the tops. Which position causes less tension for you?
When I got back into road riding after a 15 year break (in which time I was still an avid MTBer and commuted by bike every day) I got terrible headaches a few times, but these went along with a very stiff and sore neck (particularly at the base of the skull). Typically happened after a 40+ miles ride with a fast bunch, long pulls in the drops to 'prove myself', and probably a bit tense riding in paceline and echelon after such a long absence. While my legs were fine, my neck simply wasn't used to the lower position, or to being relatively static for long periods.
I did some stretching, gentle resistance exercise to build neck strength, and made a conscious effort to ride more relaxed and vary my position more frequently and the problem went away.
