I too have this same issue, as a matter of fact I am typing this a 4 am from not being able to sleep. This has been going on for about a month, but i have had it on and off for years. I was once diagnosed with RA and was taking enbrel which cleared this and hand joint pain. I am a 36 yer old male with small bones for my 185 lb body. Blood tests proved i didnt have ra so I will list a few things that we will see if anyone else has anything in common.
My ankles and wrists feel fine until I lay down for awhile
I lay under a wall heater with a ceiling fan pushing down hot air
I take Ultram and NSAIDS for my leg pain from a back surgery they also help tame this pain
I have an allergy to dust mites (makes me congested, but I think my bones ache from it too)
The pain throbs in all 4 areas and feels a bit better when i stretch my ankles and crack my wrists
My fingers hurt but not as bad, I dont have any other joint pain in my body
I play racquetball almost every day
Let me know if anyone else experiencing these issues have anything in common, I am starting to think its just a part of getting older and I should get something to help knock me out when I go to bed.
