Usually back pains at my age, but because I do a lot of running that tends to aggravate it and the problem is further compounded by the mattress I'm sleeping on. Luckily that will eliminated shortly, as my normal mattress is arriving soon and that eliminates all back pains
Sometimes I lose feeling in my top thumbnail as it got squashed in a lorry door a couple of years ago and damaged the nerves, strangely enough the nail on that fingers grows harder and stronger than the rest.
Used to get aching knees from running as well, but over the last year they've really improved, could be due to the fact I put better cushioning in my running shoes.
