Can MRSA (methillian-resistant staph.) have lingering effects?

Last year, for 3 months, I had MRSA. I don't work in a hospital or jail, am not an athlete and have no idea how I got it. It manifested itself as an ingrown toenail that would not heal. I had a hickman (heart) catheter for 30 days that I self-administered IV antibiotics through every 12 hours. I experienced a 40 lb. weight loss, fevers, extreme fatigue and more. I have read that once you're cured, it's gone. But I am wondering if it has lingering effects, like a comprised immune system or continuing fatigue. Thanks.
