Hi is anyone having problems with ibandronic acid? I've been taking it for five weeks now and at first it was fine but for the past two weeks I've had lower left side back ache and on an evening I get sniffly and go hot and cold I also have had trouble sleeping The backache is not painful it's more that I'm aware of it Has anyone else got the same problem? By the way im also taking Anastrazole and am totally fine on it After two months I had insomnia for a month but am now fine I started off with Manx brand but Accord caused the insomnia now back on Manx and no problems at all
