Why Am I Feeling Swelling On Head?
Thanks for the query.
You mentioned head injury three years ago and depression. I would like to know, are you on any treatment for depression. Please do not mistake me. Your problem may be related to side effects of medication, if you are taking any.
As you mentioned 2 days ago the hat fitted you but not today may not too important. The possibility of adverse drug effect is not that strong. The possibility that you are under treated. I do not think a hair cut is the issue as well. If you feel so you may try getting it done and retry wearing the same hat.
Please give me a detailed history of any medication you are on. You may wish to XXXXXXX your treating physician once, he must be able to notice apparent swelling if any.
Hope I answered your query.
Feel free to ask, if you have any further doubts.
Wishing you good health.
Thank you.
