Sound sensitivity, Ear pain.

Left Ear pains inside and feel blocked at times. Pains especially if I listen to something on headphones or if some loud noise/ sound there. Higher pain if sound comes from left side. In general loud sound is painful, stressful and uncomfortable. After Left ear pains on sound sensitivity, it leads to left head back top corner throbbing badly I had black wax blockage in left ear few years ago and couldn’t hear from that ear I had TMJ pain and difficulty chewing due to that, mainly on left side around a year ago. any drops I can put when I feel my ears are blocked or irritated? I avoid earbuds or use them only for space in between just below ear opening, making sure I avoid pushing it inside. Anything I can use/ do for sound sensitivity? Please advise as I am unable to visit EnT right now. Thanks
