A brief history first.I did 2 three day very hard blocks of training then went on holiday did a short run on the first day of the holiday then again on the second day after that a long walk with no problems then on the third day my thigh muscles froze up whilst walking by froze up I mean I was in great pain,unable to walk more than a couple of steps then try to strech them then walk on.This continued for the rest of the holiday only large doses of ibuprofen making a difference.
I,ve just been out on the bike now to try to pedal it off? but spent most of the time lent against the bike in agony.The muscles hurt to the touch I ,ve tried massaging them.I find that I cannot tense the muscles when they are in pain. Please help!

Sounds like you’ve over done it. Rest and good sleep.

Possibly rhabdomyolysis. Likely to resolve without intervention but perhaps see your GP (especially if any other symptoms).
