It sounds like your headaches are due to stress to be honest or even allergies. My fiance gets head pressure when he doesn't get enough sleep or when his allergies kick up. Stress can also give you those types of headaches, so you should try and just breath
- I know it can be hard though!
For it to be sore is very normal! Some places are more sensitive than others and it sounds like yours was in a sensitive spot. My foot one hurt a lot more than the ones on my back
. Along with the one that was on my thigh (I think that hurt the most!). As long as you keep it clean and it's not creating any puss or signs of infection, you should be fine!
