Hi Swilly. I just posted something very similiar. Have you gotten an answer yet? My pain started about 3 wks back, first my tail bone hurt so bad I could not walk, lasted maybe 5 min. A few days later my left ankle hurt so bad I could not walk, felt like it was going to crack...in the am it was fine. The next day I was running stairs and my right foot hurt so bad including toes, thought they were being crush...was fine an hour later. Have had pains in different parts of my spine. I have had short quick pains in all of these areas too.
This scares me I am 33 and paranoid its bone cancer!
However, I learned aciphex can cause deficiencies and can cause osteoa, but I was tested for RA it came back okay. I have been on aciphex for 1 yr....maybe it is a def., not sure. Also had a cbc and was tested for lupus--both okay. I get my other labs next week.
Oh joints have been cracking A LOT and knee feels like its about to pop out when I excercise
Does this sound like your pain too? Its very scary!!!!
