Anyone had muscle spasms whilst on AIs?

I know that aches and pains are a side effect whilst being on AIs, I am on Letrozole but in the last month I seem to be having muscle spasms.
I had 5 years of Tamoxifen and no problem and now on year 4 of 5 years of Letrozole. I feel like a 90 year old when I get out of bed and have started going for a walk before I leave for work just to loosen things up but these muscle spasms are something else, not all the time but if I move suddenly or bend down they catch me round the lower back.
When it first happened a few weeks ago my GP gave me diazepan and pain killers to loosen the muscles but I have tried to carry on without going back to the GP.
Any ideas or inforamtion would be a help, I am off to see my Onc next week. my yearly checkup, so am going to bring it up then.

Yes, spasms around and under my mx scar/ribs. I put them down to rads. Leg cramps also a problem. Feel at least 90, but was told by oncologist at last visit that there “is no choice, and have to continue”. Lovely.
I don’t have joint pain, but generally ache all over with a flu-like feeling when over tired. I have put a lot of weight on round my middle, and I have been trying to walk every day. Cholesterol also up, so am expecting that treatment to start as well.
This weather is not helping my resolution to keep walking - soo cold.
Back to the spasms - one for the oncologist I think, as this is presumably down to the nature of the drug (or alternatively nothing at all to do with it!!)

Thanks Karis, yes the problem with my Onc is that he doesn’t want to know about SEs, still at least I am getting a lot of fresh air in the mornings!
