Hello, Thanks for your query. After going through your query I came to know that you hurt your ribs during wrestling and mixed martial arts when you got kneed in your lower right ribs. When it happened you lost air and you had enormous pain coming from your lower right rib. After 4 months it started feeling better and you had full flexibility with very little irritation from your ribs. You wrestled on 8/29/14 and you started to feel the same amount of pain from when it first started. It really hurts and it is starting to hurt as you take deep breaths. You want to know How you should deal with this and How long will it take to finally heal. In my opinion you got fractures of rib at that time . These fracture has united but has not consolidated (solidified).It may take few more months time (say 3 months) to consolidate so you should avoid strenuous exercises till then.Now because there is pain so take rest and and analgesic such as diclofenac (three times a day after meals) till pain subsides. You can discuss with your treating Doctor about it.I do hope that you have found something helpful.If you have additional questions or follow up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health.Take care.
