For the last week, I have had recurring headaches. I was curious to know if headaches can be due to neck and back strain. I just started playing fastball and my neck , back and arm are so sore. I'm wondering if its most likely related to being so sore and stiff and due to muscle strain. I noticed that they started when I started playing ball again. Also, I have been taking very strong Advil as well as Tylenol and still feeling the head pressure and headache, which makes me think its due to being so sore. Thanks so much for taking the time to read my question :)
