I dont know whether this has any relation to your question?
Backpain oh yes I've had my fair share. Thirteen years ago diagnosed
ovarian cyst,(removal left ovary)..Then 5 years ago back pain resulting in
a lumbar disc hernia (rupture due to ware and tear so they say!).. Operated on 3 times, and then found on MRI scan another cyst on my remaining ovary..sub total Hysterectomy 2004.
Put on oestradoil HRT tablets.
Then found out 6 weeks ago I had underactive thyroid..WHAT EVER NEXT!
So Yes I would say go an have tests, scans etc just incase it is related
in any way (oh and I was on the contraceptive pill for 10 years????)
So I was wondering also as to how long I have had a thyroid problem and not
known about it.
Any way hope this may have helped?
