Have had a very bad back from Saturday after trying to lift my 5 year old grandson as he was upset. I had a phone consultation with Dr this morning and she has given me condene. Haven't taken any yet, husband has just gone to get prescription and I have been reading side effects, one of them being slowing breathin down. I have a slow heartbeat around 47 - 52 when not in AF so a bit frightened to take them, there also seem to be other bad side effects. I am on Apixaban so can't use the usual gels. Has other forum members used condene or could recommend any thing else I could do. Wouldn't usually fuss over a sore back but this one is terrible, can't sit, lie down or walk, just moving between the three. Thanks in advance for any help.
