Have an interesting time line here...got a home gym for Christmas 08. Use it a lot, like it and the results. Time line is that since lifting almost to the week I started, when I sleep, my hands and mid forearms fall asleep if they are under my head or in the vicinity. If I sleep on my back with my hands to my side, no problem, except I cannot sleep 7 hours on my back. Now, three days ago while lifting and pushing it pretty good, I get a sharp pain in my head..very centralized and painful..stopped lifting..tried again ..same results. Took a day off, tried to lift yesterday, very little strain, light weight, same thing again, strong centralized pain in my head. Has anyone experienced this? are the two related? Thanks in advance, and btw, I have a Dr. appt. in 3 days, but kind of curious if I am that abnormal and if my gym is gonna ever be used again?
