I know that this problem has been discussed many times here on the site - I just wanted to complain really. I did my first run yesterday and felt great after a nice hot shower and some modest stretches recalled from my PE cool downs. Today however my calves feel really stiff and tight. It's not painful, just uncomfortable and it eased off when I walked to Asda. All I really want to know is - could this be a hydration thing? I don't feel thirsty unless the air is really dry so I often forget to drink and dehydrate to the point where I have technically overdosed on my meds and start hallucinating. Also - because of the same meds I can't take ibuprofen or other non-steroidal anti-inflammatories (NSAIDs). If my calves do get stiff to the point of painfullness (unlikely I know, but I like to be prepared) is anyone else in the same situation and what have you done to ease it?
