- Persistent phlegm symptoms may be due to post-nasal drip/allergic rhinitis and I feel that consulting your doctor to have a good history taking would help clarify the cause and treatment plan. As Dr Paul suggests, reflux may also be a possibility.
- Blood in semen, it really depends on the frequency, duration of the symptoms. Prostatitis is a possibility, albeit usually you would be more unwell and have some discomfort in the perineum. UTI/STDs are also usual causes, after trauma has been excluded. Do see your doctor as well if the symptoms persist as antibiotics may be indicated.
Hope all goes well!
