Hi everyone,I've just come back from Tenerife. I got home at 3am on Wednesday morning,went straight to bed & was woken up with the most painful spasms-cramp in both feet & legs,it really was bad. I had to get up but could barely walk & I felt quite ill,head spinning & really faint. I feel better today but legs & feet still ache although no more cramps. Anyone got any idea what it is or what I should do? I also get so tired after travelling is this all part n parcel of this dreadful condtion?
