hey everyone, I'm new to this forum and have a question. Whenever I seem to workout my upper body (namely chest and shoulders). I seem to get a strenuous pain in the lower part of the back of my head. This is then followed by a pain on my forehead if I continue and finish my set. This pain usually comes while doing exercises such as Bench Press, Military Press, and sometimes pushups... I'm not quite sure what it is, though I know that it started when I was using a weight machine (attached weight) to do inclined bench press, without warming up first... If anyone has any suggestions, it would be greatly appreciated. Thanks and I hope to hear from someone soon.
