Hi, I was diagnosed with costochondritis a couple of months ago and have been having chest pains on and off since then. I also get random feelings of numbness and tingling in my knees, elbows, and sometimes in y chest. I can t tell where exactly the feeling comes from in my chest. Sometimes it feels like its in my breasts sometimes it seems deeper. I don t know if I m just being paranoid of if there is really something more wrong with me. I have been in to see my doctor twice and have called many times to update him on my condition and he just seems to brush me off, which makes me think I m just over thinking my symptoms but it s beginning to cause a lot of anxiety in me and I know that can make it worse.I just don t know what if anything is wrong with me. I I just don t feel like myself right now and want to feel normal again!
