Question: can antidepressants be useful in helping with recovery from PCS symptoms, such as a mild headache and tinnitus? My mood is not really the issue - for the most part, I've been holding up reasonably well (other than occasional mild depressive/anxious feelings when symptoms flare up). I'm at the 5.5-month mark since my injury, and have been gradually making progress. Overall, I'm now around 7.2/10, and had a couple of good 7.3/10 days last week. My headache has gradually lessened, my sleep has improved, the setbacks have fallen off considerably, and my bounceback time from symptom flareups is better.

However, I still have some remaining issues, mainly to do with exertion:

- Mild headache - it mostly doesn't bother me at rest and is typically around 2/10 in severity, but it still tends to flare up from overexertion - for example, from walking for more than 20 mins, traveling to appointments or overdoing it cognitively

- Tinnitus (relatively mild and tolerable at rest - usually no more than 3/10 - but it can also flare up from overexertion)

- Mild insomnia and tendency to oversleep (eg, waking once or twice, sometimes weird dreams, getting up around 9 am instead of my usual 7 am)

- Occasional anxiety/"off" feeling/edginess (again, this is generally not an issue at rest, but can flare up from overexertion or stress)

So, my questions are: might a low dose of an antidepressant (or other medication) help in reducing these symptoms and improving functionality, or at this point would it be better to hang in there without medication and allow the body/brain to heal on its own, however gradually? Any other recommendations to help build up exertion tolerance?
