My health is increased by 5 hit points and I can't figure out why. My health bar currently shows 235 hit points and it's colored in green as if I was wearing a health increase item.
I don't wear any items or have any spells on me that should increase my health.
I play on PC if that makes any difference.
Any ideas? Thanks.

Check active effects in the menu. My guess is you're overlooking something with a health buff.

The blessing of Arkay increases your health by 25 HP. You might have that.

I have triple checked active effects, don't have anything like that. This has been bugging me for the past few days since I noticed it and I tried different blessings, unequiping gear, etc.
It's irritating to say the least.
