im 16, and my doctor said i have psoriatic arthritis. i think hes wrong. the lower articulations in 2 fingers hurt, and every so often some months, it switches to 1 or 2 other fingers and it ends in those (that is from that arthritis). next, the doctor told me my nails were tipping or something like that, i forgot the name of that action, yet I dont think hes right my mom and i, and my friends and i checked the nails and we all have them exactly the same. next, i dont have anything of psoriasis. the little red things u get in your forehead/head, no symptoms at all of psoriasis. do u think my doctors wrong?
