Phyldelux, that sounds just like me. Same age as well. Before menopause kicked in this time last year I was well on my way to getting my degree in IT - I only had a months work to go. Then menopause kicked in. I think if it had just been the mental slowness I would have coped. But, I also got the physical problems of hot flushes, 'crawling' sensations over my skin PLUS what you described - the pains in my lower leg area. It seems to be more like the tendons/muscles rather than the bone. If I push on my achilles tendon (at any time) its really sore. Its at its worse when I first get up and after sitting for awhile then lessens after about 10 minutes but it never goes away completely. I stopped going for morning walks as I thought it would be aggravating the problem but it made no difference so I've resumed - its still painful to walk but not getting any worse.
It seems to be directly related to meno as thats when I first noticed it. I hope it goes away when meno is over (whenever that may be!). Has anyone had this? and (a) is there a way to lessen the pain? (b) does it eventually go away?
