A doc that actually touches and and checks for muscle tightness would be one way... but they don't usually do that these days .. it's all testing & imaging...

If you can ask for or find some expert physical therapy or perhaps expert chiropractic care, or just an evaluation..
Both PT & DC usually can/will assess for muscle soreness and soft tissue problems..

You may just be having some muscle spasms that need some massage, ultrasound or IF stim etc..
The head bumps could be referred pain from trigger points or spasms.
