Peyronies disease is not serious but may make intercourse difficult and painful. So far there is no disability, don't treat it. Tamoxifen is good for pain. The treatment is need based. If you want to have intercourse and is not possible due to curvature, get operated. In your case, few stitches on opposite of curvature should cure it. There will be not complication except slight shortening. Most of the urologist will be able to do it.
