Welcome to Healthcare Magic'
Since you suffered from trauma and your urinary stream has weakened, burning sensation on passing urine and bending of the penis has occurred it suggests that there has been slight bleeding on the outer coverings of your penis which is now resolved and formed a contracted tissue causing a Chordee. The pain could be associated with the chordee or a mild stricture formed inside the urethra
. You need to consult a Urologist
who will be able to examine you and tell you if this can be resolved on its own or require surgery to make you feel better. As of now drink plenty of water. Consult your Urologist and get examined for stricture.
