I have read a comment on this forum that we shouldn't be giving medical advice. I had numerous doctors, surgeons, nurses, oncologists and a pharmacist trying to work out a solution. I was sent home from hospital with the same stuff I had in hospital that didn't work. I still took it as I was instructed however the lovely ladies on this site gave me more 'medical' advice which I followed. I was pacing the floor from 4am to 7am in excruciating pain in my legs. Then, the first shuttle landed! Thank you my lovely friends. I will be doing more of the same today to land that second shuttle. Hopefully there isn't a third shuttle up there. Experience is often the only answer, not text book knowledge. Hugs and tears of gratitude.
